event horizon was creepy as hell...

but to me, one of the scariest movies i've seen (and i know it's not a horror flick or anything), was requiem for a dream. holy fucking shit i'm not doing hard drugs. ever. that was so scary, and the end is just heart breaking. i know that's not what you're looking for lol but in my opinion, that's one of the scarier movies, because of it's gritty reality...that's actually happening to people.

the descent was creepy as hell, i mean, watch it and imagine that happening to you holy fuck it made me jump quite a bit when i was watching it.
