Weird, Disturbing, and/or Controversial movies?

The movie itself is about a pedophile who returns to his hometown after serving jail-time in an attempt to start over with his life. The scene is at the end; Bacon's character is at the park and starts up a conversation with a little girl passing along. Over the course of their talking, he convinces her to sit on his lap. Nothing extreme happens, but just the expression on his face and the way he interacted with the child gave me a cold, sick feeling.

wot with the kiler killing chilldren in horrific ways then posting vids demanding money for there safe return after he had already killed them then the parents of all the fammilys killing the guy with aload of knives swords scissors axe's and other such wepons.

The killer kidnaps his victims. He's got a website where he shows that person in a life or death situation. The more visitors he get, the faster the victim will die...in a very gruesome and disgusting way, I have to say. I almost couldn't handle it.

its about two collage students who make a zero gravity machine and go back in time and they have to work out were and when they fucked up because they have toattaly fucked up everything! it's a bit of a phisics nerd movie but it is fucking amazing all the same.
