I wish we could let his subjects talk more - I have a hunch that what they would have said then would be a lot funnier.
As it were, most of the interviews followed the following template:
Interviewee: <some insanely crazy stuff>
Bill Maher: "You can't seriously believe this crap..."
Interviewee: Yes I can...
Bill Maher: C'mon... You can't.
The one moment I really enjoyed was the interview with the senator from Arkansas, Mark Pryor, where he says that one doesn't have to pass an IQ test to get into the Senate. The absolutely priceless part is watching him right after he says it, and see how he slowly realizes what he'd just said, as the smile fades away from his face...
The other were a few quotes from Founders, to illustrate what they actually thought about Christianity (that the United States of America was founded as a "Christian nation" has long been the working theory of the right wing, and a platform of Texas Republican Party).
Here are the quotes:
Lighthouses are more useful than churches.
-- Benjamin Franklin
Christianity is the most perverted system
that ever shone on man.
-- Thomas Jefferson
This would be the best of all possible worlds,
if there were no religion in it.
-- John Adams
Of course, the movie will not win any converts. The people who believe in the "talking snake" will probably never even see it. But as far as the entertainment value for the people who don't - I would say wait for the DVD.
