Yesterday, I watched Bill Maher's Religulous. I did it not because I want to disprove religion, which he does, and Islam, and Judaism, but I wanted to know what he was all about. I did know a bit, but it's just really interesting to see public figures and paid religious professionals stumble and bumble with questions with obvious answers if they were really honest. But they can't answer the real answer because it doesn't mesh with their lifestyle.
One section I found particularly interesting was the chapter on the DVD entitled "God and Country" if I remember correctly. Bill started the section by asserting that in Jesus' world view, there is no room for nationalism. This is one point where I agreed with Bill immediately. As a true follower of Jesus, there is no "God and Country." There is only God. You want to be a patriot, whatever, but your allegiance lies with God alone when it all comes down.
If you like to see religious people squirm, you'll like this movie. Beware, if you are a conservative Christian, or a very religious person, this movie will make you squirm. It made me sick to my stomach to see all these people claiming to be Christians rather than defending the truth, defending their religion. It was horrific to hear all the really bad answers.
Overall, I'd give this movie about 7/10 based on how it was done, editing, writing etc. But if you are a Christian, this is a must see just because you need to be exposed to this kind of thing.
