One of Stanley Kubrick’s masterpieces. This 1971 movie, based on the book by Anthony Burgess, is the movie that made me want to be a critic, because it disturbed yet impressed me at the same time, and I kept returning to it to figure out why. (The answer: It’s a brilliant piece of filmmaking, basically.) Malcolm McDowell stars as a futuristic teen thug who, over the course of the movie, experiences being both predator and prey.
