"Religulous" doesn't answer too many questions, just affirms doubts
Content-wise, it's best for high-schoolers struggling with the concept of religion, though Maher, in that smug attitude of his, is hilarious but completely one-sided. Any argument the religious people bring up he shoots down with hardly a refutation. That said he does show the ignorance of some of the zealots. If I had to go with labels, I'd consider myself agnostic, so naturally I sided with Maher more than the interviewees, so I may have liked it more than some. Content-wise: CSM is wrong in the language, there's only some really strong stuff scattered here and there, but there's a bizarre pornographic/sacrilegious image thrown in there that makes this purely 17+.
