[Movie] Most disturbing movie

I'm a bit of a mouse when it comes to disturbing movies.

I remember being slightly disturbed by Kill Bill vol. 1, but that was all circumstantial. It was 5:00 AM, i had watched nearly 15 hours of straight movies before then, i was totally fried, and really out there mentally. After a while, i started to feel sick watching the movie, looking at all the "blood" and thinking that it would be possible for a person to be capable of this. The next day i realized how much i was over reacting to that movie, and if i saw it again, it wouldn't hit me nearly as hard.

After that it's just scenes from movies, as opposed to entire movies.

Jam it back in, in the dark.
