[Rotting Eye]

Well, this is just off the top of my head, but three parts in Event Horizon.

1) When the kid jumps out the air lock and starts spewing up blood.. Watching that was painful.

2) When what's his name turns around, and has his eyes in his hands.

3) When the crew finally gets the old ship's logs to work, and they watch the crew killing themselves.

I dunno why, but those parts were just.. disgusting.

And for some reason, The new House on Haunted Hill bugged the shit out of me. It was the only movie that's made me sick to my stomach after I was done watching it.

Seeing the rooms smeared with blood, the girl chopped up in the cabinent. Oh, and when the dude enters the spinning chamber and starts flippin out, and seeing crazy shit. And the big vat of blood that the dude almost gets sucked into... Ugh. Oh, and all the nasty looking things in the displays. Like the horses, and people.. Wahh I HATE that fuckin movie.
