This movie is by far the greatest documentary that I have ever watched.

You can watch it free at http://www.zeitgeistmovie.com/ where you can watch it from the site or download it.

The movie is broken up into three parts. The first is on religion. Second is on 9/11. And the third is the federal reserve bank. Regardless of whether or not you watch this first part, which is my favorite, the others will be a good watch.
