I don't know - Is it the funniest movie around? it is really funny, but I feel that it is more courageous than funny. Also, congratulations to the production company and distributors who must have known up front that they would alienate a certain portion of their viewership
Bill Maher did a very nice job of blending his charming satirical take on religion. Director, Larry Charles keeps his sense of humor throughout. I would recommend this one.
