Simply put this is a great movie. And one that was years ahead it's time dealing with the now so popular "serial killer" theme. But most interesting about the movie is the way it makes you think about the moral aspects of the death penalty. Friedkin simply shows and lets the viewer make up his /her own mind about it. That's why it succeeds: it doesn't want to teach you a moral lesson or oversimplify like most Hollywood fare does. And on top of that it has a wonderful Ennio Morricone score.
