Even in unrated version there is not much. Rape scene is intense but not to the point of being disturbing... LHOTL is an intense movie, not disturbing.. Have you seen "Guinea Pig: Flowers of Flesh and Blood"? It's a Japanese gore/slasher flick and it's really sick..
Nope, I couldn't find japanese movies. Maybe I'll dig deeper. Some say japanese movies are the master of gore/horror movies. Also I like movies, not documentary, because documentary has no story.
