AMAZING comedy for the non-religious, and those who are not easily offended
I love DeNiro, too, and I thought he was exceptional in this movie.
He went the extra mile to really step out of his element and make this character hysterical.
I think people are far too uptight to step out of the box of Will Farrell or Seth Rogan comedy these days. This type of comedy pushes the limit and steps over it. It's UNSAFE, which is exactly why it's exceptional. Comedy isn't meant to be politically correct, it's meant to be edgy.
I would rank this movie right up there with Freddy Got Fingered, Orgazmo, and That's My Boy. A rare, politically incorrect exception to the status-quo.
