7. Alien vs. Predator: Requiem (2007)
The idea should have worked. Aliens exist in a small town in America and a Predator comes down to try and destroy them all. Aliens fight Predator in your hometown. And yet the movie can’t come close to living up to that potential with flat characters, a stale story, and action and gore meant to cover all of it. There are moments of glee, but they’re few and far between.
