Also don't miss out on War of the Worlds, many people hate it but I thought it was good. They really managed to make the tripods scary, and some scenes of slaughter you won't easily forget. Another we are screwed recommendation: 30 days of night, made by the same director as Evil Dead. It's about a small town in Alaska, vampires, and 30 days of night. Expect a lot of gore. You should also see the Mad Max movies, desolate violent fun, especially the second.
