A Clockwork Orange
This made me so uncomfortable and I love it. Its very graphic but that is crucial to the narrative, its not just thrown in to make the movie more mature. Everything fits together so well, the story is perfect in every way, you couldn't make it better if you tried. Amazing characters and the development they get is fantastic. My favourite part would probably be when Alex gets blinded, betrayed and arrested at the mansion, its so welldone, its not obvious but theres hints that it was coming. I think I understand the movie, the message and the theme but I've probably got it wrong in some way. It's great but you already knew that.
