I just saw the movie at the SXSW film festival with my daughters. We loved it. Not only because it is delightfully weird but also because it's funny, very funny, even by "mumblecore" standards. (The director is a founding member of that movement. Google it if you've never heard of it.)
It's one of those daring little flicks that grabs religion by the balls and shakes it left and right until it pukes. And then there's the acting. Excellent, considering the uniqueness of the script and the irreverence of the subject matter. Father Billy will crack you up in just about every scene.
If you're into odd and peculiarly funny stuff, this movie is a must see. But if you're one of those folks who gets easily offended when artists mess around with religion or religious institutions, don't bother. This movie may kill you. Just consider this as a warning: The movie features a song called "God will f... you up". Now, that's irreverent. Keep an eye on this movie if it plays in a theater near you. I doubt it, but you'd never know. God works in mysterious ways. LBlancoNazoa
