I suppose with Audition, if youre after gore porn (which I never am; not my thing at all, dont really know why I watched it) then its quite tame, but it is pretty utterly and totally $%ed up, considering whatsherfaces traits and habits.
Itchi was just cartoonsih nonesense start to finish. Bored me senseless.
Since we're on the topic of extreme asian films, Visitor Q is probably the most $%ed up film I've seen. If you can stand to watch it, which I really dont recommend you do. The only thing you'll get out of it is a couple of hours not back. Its not gory or anything its just disgusting and leaves you going 'huh? wtf was the point in that?'.
