Great documentary! George Carlin was one of my favorite thinkers, and no one has or probably will replace him. He was great at pointing out hypocrisy, and putting things into perspective. I love that they incorporated things he talked about 30 years ago, that are still true today. Even more now than when he talked about them. This is an important documentary for anyone that is a fan, or has yet to see his work. I've been a fan most of my life, have seen all of his HBO specials, saw him perform live, twice, have seen a bunch of biographical specials about him, and own all of his books including Last Words which was released posthumously, and written by Tony Hendra (who worked with Carlin on it until his death). Even this documentary had things I didn't know. ...and those saying that this documentary is liberal propaganda, don't realize that his work always pointed out what the documentary covered. They probably didn't flinch when he pointed out the hypocrisy of some environmentalists, but can't get past his stance on pro-lifers, gun control, police brutality, racism, capitalism, and religion. It's the old double standard, "I was enjoying when he was making fun of the things I don't like, but he went too far when he made fun of the things I stand behind." This is a great documentary for George Carlin fans, and anyone with an open mind.
