4. A Clockwork Orange (1971)
At times a Clockwork Orange can be downright uncomfortable to watch - although it was made over 30-years ago it is shocking and unsettling to this day; directed by Stanley Kubrick, he actually had the movie banned in England until after his death. Alex (Malcolm McDowell) is a charming but violent sociopathic young man: after a brutal home invasion (where he beats a woman to death with a giant penis), he is arrested and sent to prison for rape and murder, where he volunteers for aversion therapy in order to cure him of his violent and hedonistic tendencies. A Clockwork Orange shows how much a problem violence is but also that there is nothing anyone can do about it. Even worse, random acts of violence are like lightning they can strike anyone at any time and there is nothing that can save you. It's just not the violent youth, but what is terrifying is almost anyone is capable of horrible violence with the right motivation. A Clockwork Orange shows that even in the future, the barbarity of man is what we should fear. Kubrick shows that someone could break into your house and butcher your whole family and that the solution doesn't fit the crime. If they even catch them.
