I have a likeness for sick, twisted movies, for some strange reason. Some of my favs are Hostol, Saw, Devils Rejects, that's all I can think of as my brain is numb.
Another fucked up one i saw was Taking Lives, with that Angelina Jolie chick. Watching that guy cut off his mothers head was just messed up. Plus, Jolie gets naked in the movie, so it has 2 upsides. Ha ha!! ;)
