Have you seen the entire movie yet?
At another forum where I am a far more frequent contributor it is referred to as "The One True Movie" because, without fail, someone is going to bring it up every couple of days. Usually preceded by something like "I've found something that everyone HAS to see. It will totally change the way you view the world."
Actually, it's all very interesting, and does bring up some interesting points. It is, however, chock full of exaggeration, supposition, and factual distortion. Not to mention the fact that it really is three different movies in one.
Anyway, the entire thing:http://www.zeitgeistmovie.com/
