i don't normally watch hollywood crap like the hangover franchise but some sex scenes are essential to a movie, and are not necessarily meant to arouse. monica bellucci's rape scene in irreversible showed how horrible rape is and how it can destroy a good person's life, including those around her. only perverts would get a kick out of watching that. it won't have the same effect on the viewer's psyche if that scene was cut.

because of that though, this film is in the list of movies i will never watch again.
