11. Left 4 Dead
You know what's great about Left 4 Dead? Running around killing zombies with your friends. Take out that element. Now you're watching a movie about a bunch of people that you neither know or care about killing zombies together while they try to survive and get the hell out of the city. You know what that sounds like?
Every freaking zombie movie you've probably seen in the last 5 years! Seriously, once you take out the interactive element of Left 4 Dead there's really nothing that has it standing out from any typical zombie flick aside from having some different flavors of zombies. So unless the screen writers add in a whole bunch of new elements that make the story something it isn't, all we're likely to get is just another zombie flick with characters that we recognize, but have already had a better experience with.
