Religulous surpassed my expectations. It was quite delightful. I'm a big fan of Bill Maher -- especially his stand-up -- and the film was somewhat of a stand-up documentary. Even the scenes from the trailer were funnier in the film as there was more to them.
Have you ever been to a film where there's so much noise in the audience that you can't hear what's being said in the film? That was my experience with Religulous -- but in a good way. People, myself included, were laughing so hard and so frequently that I missed out on a lot of dialog.
I'll definitely see it again (again, big fan of Bill Maher). I'm looking forward to the DVD to see all the bonus footage. I read that Rael was supposed to be in the film, but I didn't see him, so hopefully that will be there.
