Re: Most disturbing movie you've seen?
I don't care to watch gross-out films on purpose. Although I've heard about Salo, Serbian Film, and Cannibal Holocaust I never actually saw any of them and don't intend to. Last House on the Left was probably as disturbing a film I've ever seen and even that wasn't really that bad.
There was another movie, a foreign film, where a guy shrunk down and crawled up his wife's cooter. It wasn't disturbing so much as a "wtf" moment. It was a borderline fetish scene. Watching it in class probably didn't help.
