You got it all wrong dude. I haven't seen neither of those movies. Just fragments. But you won't tell me that "AU" series has message cause it just don't. Oh yeah, maybe just that some people are just heartless beasts. Maybe Salo has, I don't know but it's just disgusting.
As for what I look for in movies. I look for twisted movies but in a different way. I love mind fucks for example. All Lynch shit etc. I love movies in which nothing is what it seems. I love movies after which I'll have them on my mind and I'll think what the movie was really about. I like all kind of movies like you see. Simple hollywood mainstream slashers, dramas, comedies, mind fucks etc. But I just don't like sensless underground porn gore flicks and nothing is going to change that.
