In my high school everyone used to talk about this film that was called sado 120 days or something like that and one day I saw it with my friends because it was supposedly one of those "two girls one cup" kinda things
Well, lets just say that THIS movie def takes the cake for the most effed up **** I've seen in a film...it almost seemed real too which freaked me out more
Dear Zachary: A Letter To A Son About His Father is traumatizing in a much different way than most of the movies you guys are listing. Its a documentary. Don't spoil it for yourself just go watch on Netflix
