And it's pretty awesome.
Bill Maher basically travels the world and confronts believers of all religions and points out their flaws and basically rips on them. So it's obviously a bit one sided, but it's insanely funny. I mean, he gets a senator to call himself stupid, a pastor to say that Jesus wore fine linens and gold, and a man who calls him self the second coming of Christ to say he'd be good at being Satan too.
It's a pretty good watch, and it brings out very important questions that are rarely brought out about religion and points out the hypocrisy and flaws in them. It's pretty great though.
But note, he only really interview two very intelligent people about religion, Father George Coyne (the former director of the Vatican Observatory) and Francis Collins (Author of "The Language of God: A Scientist Presents Evidence for Belief") and those interviews only last about 2 and 1/2 minutes.
But in the end, it's one-sided-ness is outweighed by it's awesome-ness, and I'd gladly recommend the film to anyone who believes (and doesn't believe) in something.
