When you think about it, surgery is downright bizarre — humans cut into one another all the time to get rid of deadly diseases and excess body fat.

But the fact we don't marvel about this on a daily basis shows how advanced surgery has become. Over the last 100 years or so, surgery has become a safe and reliable tool, not to mention a necessary component of public health.

Here's a taste of what that journey looked like.

As early as 1906, doctors were performing fairly complex operations on patients. Rudimentary x-rays allowed unprecedented views inside the body, though no precautions were taken to avoid harmful exposure.

Other procedures around the time were less scientifically sound, such as the practice of regulating blood pressure with full-body suits as doctors administered infusions of medicine into the neck.

That's not to say the rooms for these grisly operations weren't impressive. Take the Ellis Island Hospital's operating room, which, even in 1909, looked fairly modern.

Earth is enormous.

With 197 million square miles of surface area, our planet is a massive obstacle course of geographic barriers that force most species to stay put.

Yet these barriers have meant nothing to some animals. They've traversed Earth with aplomb — dangerous oceans, stormy weather, and moving continents be damned.

Here are seven of the most fearless globe-trotting creatures that have flung themselves across our world, some through unstoppable determination, others by pure chance.

First up: The globeskimmer dragonfly. Although this insect is the size of your pinkie, it can stay airborne for more than 4,400 miles.

But the dragonflies occasionally stop on islands to reproduce. Their progeny then join vast, multigenerational, island-hopping swarms that cross the Pacific.

Then there's the blue whale. Other than the Arctic, these 200-ton mammals can swim nearly anywhere in world's oceans, which cover 71% of the planet's surface.

Lenovo announced its brand new Phab 2 Pro smartphone on Thursday at its Tech World event in San Francisco.

It'll be the first smartphone to support Google's augmented reality platform, called Tango.

Tango essentially looks like virtual reality, but without the headset. You look through the Phab 2 Pro's camera to see the world around you, then it uses Tango to "augment" that reality with digital objects and animations. It makes it look like virtual objects are invading the real world.

Check out what Tango looks like on the Phab 2 Pro.

Online business-to-business marketplace Expert Market has put together a ranking of the global cities where people clock in the most hours worked each year and have the worst so-called "work-life balance."

The site compiled information on the biggest, most important cities globally, then ranked them by the average total hours worked each year, using data from Swiss banking group UBS.

We’ve divided the figure by 52 to give you an idea of how much you’d have to work all year to compete (this calculation discounts holidays taken in the year).

Workers in each city on the list work more than 40 hours per week on average, with people in the top ranking city racking up more than 50 hours.

If that doesn’t sound like a lot, remember that our list discounts holiday. It also includes both full-time and part-time jobs, which brings down the average. By comparison, workers in London clock 33.5 hours a week, and those in New York average 35.5.

Check out the global cities where people work the most hours below.

T-11. Santiago, Chile — 40.03 hours per week: Workers in Chile's capital work the third longest hours of anyone in Latin America. That may not sound like much but when you consider that they only take an average of 16.6 days off each year it's not hard to see why they clock an impressive 2081.6 hours worked per annum.

T-11. Cairo, Egypt — 40.03 hours: Cairo has a reputation as a busy, bustling metropolis, and its workers are suitably busy, clocking the same number of hours as people 7,950 miles away in Santiago.

10. Bogota, Colombia — 40.3 hours: Beating out their South American rivals, workers in the Colombian capital clock 2,096.3 hours per year, with just 15 days holiday.

The most valuable footballers who have been picked to represent their countries in the upcoming Euro 2016 championships have been ranked by sports database website Transfermarkt.

The players are ranked according to their market value — a calculation that takes into account their recent performances, consistency, and potential, as well their international experience and marketability.

Germany — one of tournament's two most successful teams along with Spain — has the most players in the most valuable 17 with four. England has none.

Keep scrolling to find out the most valuable players who will be representing their countries in France over the next few weeks.

T-8. David Alaba — Austria

Market value: £35 million ($51 million)

Bayern Munich's Alaba is one of the most versatile players at the highest level. He has played as a defender for his club, but for his country is the chief playmaker and goal-scoring threat. He has won the Austrian Player of the Year award five times and is a hero back home in the central European nation. 

T-8. Manuel Neuer — Germany

Market value: £35 million ($51 million)

Bayern Munich goalkeeper Neuer is the current holder of the prestigious IFFHS World's Best Goalkeeper prize having won it for the last three years on the bounce. The German is renowned for his lightning fast reflexes and miraculous shot-stopping ability. Neuer was chosen as the best goalkeeper of the 2014 World Cup. 

T-8. Cesc Fabregas — Spain

Market value: £35 million ($51 million)

Fabregas — who currently plays his club football in England for London club Chelsea — has won two European Championships and a World Club with Spain. The midfielder has been one of Europe's star players since bursting onto the scene with Arsenal in 2005. 

Astronomers loathe light pollution, also called skyglow: a dim yet pervasive orange light that obscures a crisp view of the night sky.

But as a new study called "The new world atlas of artificial night sky brightness," published in the journal Science Advances shows, there's a shocking amount of light pollution that affects as much as 1/3 of the world population — so it's no longer just a headache for scientists.

Here are snapshots of the new map and how light pollution is affecting the people of Earth.

On a clear night, you should be able to see the Milky Way — the only galaxy we call home.

But a multinational team of scientists have created a new map of light pollution around the planet, and the results are pretty alarming.

The researchers discovered that more than 80% of humanity is bathed in light pollution, which is when light scatters off and illuminates gases in Earth's atmosphere.

Many people believe a happy career and a fat paycheck are mutually exclusive, but online jobs community CareerBliss.com has found that these two things can go hand in hand.

CareerBliss compiled its new list of jobs that can make you happy and rich by analyzing more than 25,000 independent company reviews between January 2015 and April 2016.

The reviews are from employees all over the US who evaluated 10 factors that affect work happiness on a five-point scale: one's relationship with their boss, relationship with coworkers, workplace environment, job resources, compensation, growth opportunities, company culture, company reputation, daily tasks, and job control over the work performed on a daily basis.

CareerBliss combined those numbers to find an average rating of overall happiness for each respondent, and then sorted the results by job title and salary to determine which jobs pay well and make professionals the happiest.

The No. 1 job on the list is chief marketing officer (CMO). People in this position gave the profession a "bliss score" of 4.06 out of 5. The average annual pay for these professionals is $171,000 a year, which is more than triple the national average salary of $48,320.

It's been a rough summer so far for movies. There are sequels no one wants to see, and, outside of Disney movies, there have only been a few hits. Sadly, this weekend will not change things.

Though the much-anticipated big-budget adaptation of one of the most popular video games ever created, "Warcraft," comes out on Friday, critics are telling us to run away from the movie that has Orcs and humans doing battle.

With a current rating of only 24% on Rotten Tomatoes, "Warcraft" is the worst-reviewed summer blockbuster of 2016 so far.

This could be a case of audiences and critics being split on a film, however. Overseas the movie has been out for a week and already made over $100 million. The domestic box office is certainly thirsty for a surprise hit.

But before you decide on buying a ticket, here's why critics think you should pass on the movie, which is being called a "once-in-a-generation disaster."

The CGI is at the level of (notorious bomb) 'John Carter.'

To correctly adapt a video game, you need to have some great computer graphics. That doesn't seem to happen here.

"Unlike, say, 'The Jungle Book,' which was entirely artificial yet came off as completely organic, it’s hard to lose sight of the green-screens here, especially when the warlike Orc characters, who boast some of the least expressive character design since the aliens in 'John Carter,' stand next to the film’s human beings,"The Wrap said.

"The heavy use of CGI, and its occasionally awkward interactions with the live-action elements, only serves to distance us even more,"The Guardian wrote. "Much processing power has been put in the service of spectacular, bludgeoning combat, but the images are somehow insubstantial, and we rarely feel the heat of the battle."

The acting isn't any better.

Stars including Dominic Cooper, Ben Foster, Paula Patton, and Travis Fimmel (as the lead, Anduin Lothar) all seem to be victims of miscasting.

"Travis Fimmel is a walking charisma void as strapping warrior Anduin, a sort of Aragorn without the personal charm,"Time Out London wrote.

The Playlist felt that the characters, like Cooper as the King, were "stiff" and that "their accoutrements are so overly polished they appear phony and cheap."

Some critics are comparing it to one of the worst movies ever made.

It's never good when a movie is compared to "Battlefield Earth," a sci-fi bust starring John Travolta and adapted from a novel written by Scientology creator L. Ron Hubbard.

"Imagine 'Battlefield Earth' without the verve, or the unintentional comedy, and you’ve got 'Warcraft,'"The Wrap said.

That stings. But then there's Indiewire's review, which calls the film the "'Battlefield Earth' of the 21st century."

"'Warcraft' is a once-in-a-generation disaster, one of the most ill-advised and ill-conceived studio films of this modern blockbuster era," the site said.

You hear it all the time as a business leader or entrepreneur, "your success will depend upon the people you surround yourself with."

That's true... you must find the best talent and get them on your team and in your company.

No doubt about it. But, there is one fatal flaw that leaders make in the "people" department over and over again.

In both startup situations, and among seasoned leaders, I see them focusing on finding the right people to do the work, but not giving attention to the ingredients of those relationships that actually fuel performance, and increase their own performance as well.

Ask any high performer about their best season in business or in life... or their worst season, and you will always find one thing to be true: there was another person or persons playing a pivotal part during that time. The neglected truth of performance is that to succeed and perform well, you must have the right kinds of relationships active along the way, and at the same time, you must avoid others.

We all know this intuitively, that some people affect us well and others can "do us in." But now neuroscience is able to explain the "how and why" this happens, and how to be better stewards of our relational world so that we are being fueled in the right ways, and escape the downfalls of the wrong kinds of relationships in both business and in life.

Turns out that there are relationships that actually increase performance in our brains, and those that diminish us. Knowing how this works can mean the difference between success and failure.

Leaders that I work with find this simple map helpful to determine whom to get close to and whom to avoid. They also find it useful in their teams as well. I call it the "map of the leader's world," and there are only four possibilities, four possible corners of your world, where you can find yourself in any relationship:

SEE ALSO: How having a 'work spouse' can ruin your real relationship

Corner one: No connection

This corner is the one of being surrounded by people, but still basically being "on your own." There is the absence of needs being met, an absence of real enhancement of fueling or connectedness that drives you to doing well and being better.

Ultimately, you feel like you are by yourself, and it all depends on you, even with others around you or even on your team. "Alone...but with others." It is the corner of unmet needs.

Corner two: Bad connection

In this corner, we have connection with someone(s) but the nature of the connection is that we end up feeling "bad," in some way. "Inferior"..."not good enough," always not measuring up.

This is very different than being appropriately challenged or getting feedback, for those are invigorating. This dynamic, however, is demotivating and painful.

De-energizing, as it feels like not matter what you do, it is never good enough and never reaches the bar. While in the short-term, this dynamic can fuel your efforts, over time it becomes debilitating to performance.

Corner three: Pseudo-good connection

Different than the aloneness of Corner One and the bad feelings of Corner Two, Corner Three feels "good." At least for a while. This is the connection that makes us feel good in some way....it medicates us.

The approval of someone, the flattery that makes us feel we can do no wrong, the accolades of one more promotion or adulation all feel good, but are shallow and ultimately not performance-enhancing.

A team or life surrounded by "yes" people and admirers is neither fueling nor challenging us towards improvement. It is like a "sugar-high," that feels good for a minute...until you need it again. It nourishes nothing.

Buying your first house can be an excellent test of patience, endurance and resilience.

If you’ve never been through the process before, it can certainly be an intimidating one. From scary terms and bidding wars to that tiny matter of plunking down a whole heck of a lot of money for a down payment, most people who are buying their first homes could stand to use a little help along the way.

We’ve tapped into some experts from across the country to find out what their top tips are when helping first-time homebuyers find and purchase their dream houses. Use some of these whenever it’s your turn to take a ride down Homebuyers’ Lane.

SEE ALSO: 7 common pieces of financial advice you should probably ignore

Tip No. 1: Determine a comfortable budget

Expert: Russell Vilt, Managing Broker & Owner Excel Condos, Chicago, IL

What it means: Nothing can be done when it comes to buying a home without first understanding your budget. “I always suggest speaking with a lender who can help determine their buying power,” says Vilt. “The sales price of a home is not the only expense, so they need to be aware of taxes, assessments (if it’s a condo), homeowners’ insurance, etc.”

A tip from MagnifyMoney: be sure not to let a mortgage lender or realtor talk you into buying more than you can truly afford. Just because you get approved for a $300,000 mortgage, it doesn’t mean you should get a $300,000 house. You should also learn how to hack your way to a cheaper mortgage.

Tip No. 2: Get pre-approved by a lender as soon as you think you want to purchase a house

Expert: Rhonda Fee, broker/realtor, Aspire Realty Services, Pleasanton, CA

What it means: Pre-approval will be your road map for a successful purchase, which is why it’s so important to get this part rolling right away. “Understand what bills need to paid off, and how much down payment you’ll need,” says Fee. “The lender should be someone they have been referred to by a friend who had a successful transaction with that lender, or … a realtor. A lender can kill a deal if they are not on top of their game.”

Check out this piece for more about what to know before getting pre-approved for a mortgage.

Tip No. 3: Know what loans are available to you

Expert: Tory Sheffer, realtor, Berkshire Hathaway HomeServices, Michigan

What it means: Sheffer has come to realize that most first-time homebuyers tend to know the basics about buying a home — like what a mortgage is, for example — but that’s about it.

“They aren’t aware of the different options available to them with Conventional, FHA, Rural Development and 80/10/10 Piggyback loans to help buyers who do not want to pay Private Mortgage Insurance,” he said. To help, Sheffer makes sure to take some time and explain to his clients the difference between these additional options. For example:

• Rural Development is a zero down payment program
• FHA is a 3.5% down payment
• 80/10/10 is a 10% down payment with 10% as a second mortgage to avoid PMI, which in turn lowers the monthly rate, more often than not
• Conventional Mortgages are not insured by the federal government, but more often than not PMI is required until the buyer has built 20% equity in their home. Learn more about why you should aim for a 20% down payment.

Ask your broker or lender for more specific information about each. 

You’ve probably seen Kim Kardashian-West’s instagram photo of a bloodied face in the name of beauty or heard about an array of celebrities talking up acupuncture as a natural medicine on television. Unlike many celebrity health endorsements seen today, this one might actually be a method that could yield results in people's life.

Acupuncture was accepted as a complement to Western medicine in 1997 by the National Institutes of Health, and there is an entire laundry list of health benefits.

Everyone's body is different and there have been reviews both supporting and denying the effectiveness of acupuncture, but you may still want to at least consider this natural remedy before just falling back onto prescribed drugs next time your body could use a little help.

Weight loss

The first benefit is everyone’s favorite: weight loss.

A study published in Nature in 2009 showed that acupuncture could significantly reduce body weight and improve outcomes of obesity, allowing higher weight loss than drugs or a controlled lifestyle alone. Acupuncture can stimulate certain nerves and muscles in the body and improve energy flow. It also helps to release endorphins, stopping you from craving more food and over-consuming.

Herbal acupuncture combines the traditional use of needles with burning herbs. And, according to a review of animal and clinical trials published in the Journal of Acupuncture and Meridian Studies, it is a method has been effectively used to help treat obesity, providing such benefits as anti-inflammation and helping fats metabolize quicker.

Although these results are promising to many struggling with weight loss, it is important to note that acupuncture may not be the answer for everyone. A healthy and sustainable weight loss plan is encouraged no matter what method is used. 

Drug addiction

A studydone by the University of Malaya shows that acupuncture could help addicts stay clean. This therapy can be given by manual insertion of needles or electroacupuncture. The two methods are quite similar, but during electroacupuncture, needles are attached to a device generating continuous electric pulses to add extra stimulation. Both types of acupuncture been shown to reduce anxiety following nicotine withdrawal and have been helpful in reducing withdrawal cravings by regulating brain activity. The study also says the procedure could also be used to reduce withdrawal symptoms in heroin and opioid addicts.

Chemotherapy

Chemotherapy has an array of side effects, including nausea, weakness, hair loss, and more. A study conducted at Canada's McMaster University-Juravinski Cancer Centre followed 24 chemotherapy patients for 6 months after treatment. Each was given a modified total neuropathy score (MTNS) throughout the process, and the final results were measured. Acupuncture was shown to be helpful in reducing neuropathy, or peripheral nerve damage. It was also shown to help reduce numbness after going through chemotherapy.

The Guangzhou University of Chinese Medicine released a study with 1,639 participants. It found that, when combined with traditional drugs, acupuncture can significantly increase pain-free durations and provide a shorter onset time of pain relief in patients still undergoing cancer treatment. The study also recommended combining acupuncture with traditional drugs, as this is more productive than using either alone.

With countless barbecues to attend, and tons of beers and rosé to consume, it's easy to pack on the pounds during the summer.

But by following a few simple tricks, it's possible to indulge in food and alcohol in the sun — while actually slimming down.

Registered dietitian Lauren Popeck, of Orlando Health, shared with INSIDER her three best tips for losing weight this summer. 

Load up on fruits and vegetables.

When you're at a party (that actually has decent food), it's easy to binge without even realizing it.

You grab an extra cupcake here, help yourself to a second hamburger there and before you know it, you've eaten way more than you planned.

But, if you make it a habit to eat a lot of fruits and vegetables, you'll be less likely to gorge on unhealthy treats this summer.

"You should try to fill up on as much fruits and vegetables as possible. Those are the foods that have the lowest amount of calories," Popeck explained.

Fruits and veggies can help you feel full — and they also have a ton of fiber, which is good for digestion.

The dietitian recommends eating summer staples, including tomatoes, watermelon, cantaloupe, leafy greens, squash and zucchini.

Avoid sugary and calorie-dense drinks.

When you're out in the sun, it's vital to stay hydrated. But pounding beer or rosé — or even a refreshing fruit juice — instead of water can lead to unexpected weight gain.

"When you drink something, and say it's a juice or sweet tea, your body just digests that very quickly," Popeck said. "It doesn't give you the sensation that you're full or that you've had anything, even though you've just had a ton of calories."

She added, "That can make it hard to keep within your limits if you’re really trying to lose weight and watch it for the summer."

In general, the dietitian recommends drinking lots and lots of water. But if you're craving a juice, she said you should instead drink flavored seltzer water.

And in lieu of sugary wine or beer, the dietitian suggests mixing half a glass of dry wine with seltzer, or going for a vodka with club soda.

Don't skip meals.

"In the summertime, you can get busy traveling—  or maybe you're at the beach or other areas where you may not always have meals available," Popeck said.

But if you're hoping to lose weight this summer, it's vital to not skip any meals, according to the dietitian.

That may sound counterintuitive to those who assume that skipping meals leads to weight loss. But in reality, not eating can actually lead to weight gain in the long-term.

"What can happen is if you’re going long periods of time without eating, it can make your body go into starvation mode, where it slows down your metabolism," Popeck said.

The dietitian recommends people eat every five hours or so.

"It can prevent you from overeating or getting over hungry at the end of the day," She said.

Mark Zuckerberg had $1 million in the bank at the ripe age of 22, while Larry Ellison didn't reach millionaire status until age 42. Today, they're both billionaires.

Some successful entrepreneurs strike it rich early on. For others, it takes decades.

Using an infographic from UK-based web platform Fleximize, we've broken out the age at which Zuckerberg, Ellison, Cuban, and other self-made billionaires made their first million.

Mark Zuckerberg: 22

The Facebook cofounder and CEO became a millionaire in 2006 at age 22.

It didn't take long for him to make the leap from self-made millionaire to billionaire. At the age of 23, Facebook's IPO made Zuckerberg the youngest self-made billionaire in history.

Today's estimated net worth: $43.9 billion

Evan Spiegel: 23

The Snapchat cofounder and CEO became a millionaire in 2013 at age 23.

Driverless cars will be here before you know it.

Several automakers have already showed off their self-driving car technology and many car companies aim to roll out production vehicles with driverless capabilities by 2020. Industry experts expect fully autonomous vehicles to follow suit just a few years later.

This era of driverless cars will transform our lives in more ways than one, Erik Coelingh, Volvo’s Senior Technical Leader for Safety and Driver Support Technologies, told Tech Insider.

While it’s still too early to know all of the ways autonomous vehicles will impact our lives, Coelingh, who is helping lead Volvo’s driverless car program, said he does foresee self-driving cars bringing more advantages than disadvantages.

Here are three key ways Coelingh said autonomous vehicles will improve our lives.

Roads will be safer.

In the US, more than 30,000 people die in traffic-related deaths every years. But self-driving cars could drastically reduce the number of accidents helping to save thousands of lives.

“There’s huge, huge potential in making traffic safer than it is today,” Coelingh said. “That is one of the big reasons for us that we entered this field.”

In fact, if about 90% of cars on American roads were autonomous, the number of accidents would fall from 6 million a year to 1.3 million. Deaths would fall from 33,000 to 11,300, according to a study by the Eno Centre for Transportation.

Traffic and fuel efficiency will greatly improve.

Self-driving cars will make driving more efficient on all fronts, Coelingh said.

“There’s potential in efficiency, efficiency in terms of better traffic flow, but also less fuel consumption,” Coelingh said.

Because cars will be automated, there will be less chance of accidents caused by human error, leading to less traffic congestion. It’s also expected that the rise of self-driving taxis will help decrease the total number of cars on the road, alleviating the overall traffic.

What’s more, because driverless vehicles are designed to optimize efficiency in acceleration and braking, they will also help improve fuel efficiency and reduce carbon emissions.

In fact, adoption of autonomous cars could reduce CO2 emissions produced by cars by as much as 300 million tons per year, according to McKinsey. 

You will have more free time.

With cars doing most or all of the driving, you will be free to make the most of your time spent in the vehicle, Coelingh said.

And because traffic congestion is also expected to decrease, it will likely take you less time to get to your destination, which will also help create more valuable time for other things besides commuting. 

"You as a driver, you can get back your own time," Coelingh said. "And you can use it in a better way than just staring at the car in front of you," 

According to McKinsey, commuters worldwide could save a combined 1 billion hours everyday once autonomous vehicles go mainstream. 

Boxing legend Muhammad Ali's funeral was held in his home town of Louisville, Kentucky, on Friday.

Ali died on Friday, June 3 at the age of 74 after being hospitalized with a respiratory issue complicated by his Parkinson's.

Large crowds gathered in the streets of Louisville on Thursday to see the procession, which included Ali's family, actor Will Smith, Arnold Schwarzenegger, and other celebrities.

Fans stood on the streets with t-shirts, adoring signs, and flowers to celebrate the life of one of the greatest athletes of all time.

Check out some of the pictures of the procession below.

Hundreds of fans lined the streets as the procession rolled through.

Fans caught pictures of the car carrying Ali's body.

The human population is growing at an alarming rate. By 2050, there will be almost 10 billion people on the planet. 

We've been hearing this for years, but where is the most growth happening? 

Today, Tokyo is the most populous city in the world, with about 38 million residents.

Currently, just one of the 10 most populous cities in the world is in Africa (Cairo), and only two (Sao Paulo and Mexico City) are in Latin America. But in the next three decades, that's going to change.

Movie studios regularly mine comic books for their built in audiences, merchandise tie-ins, and action-friendly storylines. They've routinely turned to games for the same opportunity. There's just one problem. Many of them are terrible. Uniformly terrible.

Players, critics, and audiences are all routinely disappointed by video game movies. With the latest addition to the genre, "Warcraft," in theaters this weekend, we've looked through the worst of the worst video game adaptations.

Was your favorite game dragged to the big screen for an unwelcome adaptation? Check out our list and see.

10. "Lara Croft: Tomb Raider" (2001)

Rotten Tomatoes Score: 19%

Lara Croft is a gaming icon. A wealthy heiress fulfilling her daredevil dreams of exploring the world, both the game and film are generalized as starring a "female Indiana Jones." Really nothing in the movies work against that except for the gratuitous shots of Angelina Jolie breathless and gasping directly into the camera. The games were updated with a more feminist, humanizing perspective for Lara and a rebooted adaptation, presumably with the same perspective, was announced starring Oscar winner Alicia Vikander.  

From USA Today's review: "This film, directed by Simon West (Con Air), is like watching a novice (like me) fumble about while playing a video game. There are quick bursts of frantic activity followed by long, enervating lulls. The digital effects sometimes impress, such as the massive stone monkeys that come to life and a spinning gizmo made of huge rotating spheres. But the look of the movie is unduly muddy."

9. "Doom" (2005)

Rotten Tomatoes Score: 19%

The "Doom" series, just recently revitalized with its latest entry, is one of the most well-known horror-shooters and stars marines taking on hordes of violent, brain-dead monsters. The movie, starring The Rock, is such a monster. The explicit gore and violence tries to trick audiences into forgetting there isn't any discernible storyline. But neither fans of the games nor uninitiated movie audiences cared. The film tanked and, thankfully, The Rock's career escaped unscathed. 

From the Orlando Sentinel review: "The movie based on that best-selling body-count game is ugly, stupefyingly stupid and gross. It has a back story ripped off from a half-dozen sci-fi movies, a Z-list cast that exists only so we can see them impaled, decapitated and worse. It has zombies beheaded by bullets, gratuitous autopsies and the Rock. And that last bit is the saddest note of all."

8. "Super Mario Bros." (1993)

Rotten Tomatoes: 15% 

Probably the most popular gaming characters of all time, the "Mario" games revolutionized the medium and gave Nintendo its esteemed position as the major innovators of the gaming world. The movie, however, was blasted as everything the games are not: generic, predictable, visually disappointing, and boring. 

From the Philly.com review: "So much like a theme-park ride that you wonder where the security bar is, Super Mario Bros. is a movie whose idea of a peak experience is to be on a derailed train as it falls off a trestle. Scenery rushes by, noise blares, characters pop up wearing new costumes that they couldn't possibly have had time to change into as they eluded their adversaries."
