A Clockwork Orange
Saw it when I was a young teen, after reading the book. I thought the movie was lame, and abusive. The disrespect Kubrick gave his audience, set the tone for punkish, no-wave movies of the 80s. Clockwork and Dawn of the Dead made me callus and insensitive to violence and gore. That being said, watch it with "Barry Lyndon", as they are both Picaresque type stories, Clockwork being a satire of this satirical form.
