There's nothing scarier than sharks. They're nature's perfect predators, improved through generations of evolution dating back to the time of the dinosaurs. That's why they make for such excellent antagonists in horror flicks, like the new pic Shark Night 3D, which tells the story of a vacationing college coed (played by the lovely Sara Paxton) and her friends as they try to escape a salt water lake that somebody has stocked with hungry sharks.

Realizing that sharks just make any movie better, our folks at NextMovie decided to illustrate this by adding some teeth to water movies that sucked. Check out their hilarious posters and tell us that they're not improved 100 times over.
