I had never heard of this so I read that thread and did some googling. That sounds pretty fucked up. I usually like that kind of thing, but even I have my limits of how much fucked-up-ness I can take in one sitting. If it's too much, it sorta lingers with you in a bad, uncomfortable way. Requiem for a Dream was one of those movies for me. As was the documentary Crumb. As was Eraserhead. You get my drift.
