I just watched it last night. My favorite was the priest he interviewed right outside the Vatican. Bill Maher brought up all these things that Catholics believe and the guy dismissed a bunch of them as bullshit. I also liked how he was thrown off the Mormon temple property, pissed off the guy who ran the Islam mosque because he was there, and pissed off the public relations lady at that Bible tourist destination in Florida for being there.
This movie is only going to piss people off who don't understand what they believe and can't answer simple questions about their faith. It will piss off people who take the Bible literally word for word. If you believe the Earth is 5,000 years old and don't believe in evolution, you're an idiot.
