I just bought and viewed the movie "The God Complex" and it was hilarious! The parody is excellent and there are some great tunes in there. I recommend it to see. Unfortunately, it can not be seen in a theatre, you have to buy it.
I would say it was better than Religulous!
This movie comes from the same people who brought us "The Submissive Jesus". Have you got yours yet? I got mine a month ago!
