If the succeed in getting back in heaven, then they will have proven that God can make mistakes. This, in turn, would wipe out all existence. Bethany is a Catholic who works in an abortion clinic and goes to church every Sunday more out of habit than faith, but she decides to help. Add all this together, and you've got a somewhat shockingly good movie. Make no mistake, the shock value of this movie is high.
Characters spew obscenities like they're going out of style.
God is a woman, Jesus was black, the Bible is sexist, God likes to come down to earth in human form to play skeeball of all things. It also compares the Catholic Church to a public-relations firm that is trying to hook people on religion the way tobacco companies have hooked people on cigarettes. There are a multitude of pop culture references in the movie, everything from Harrison Ford to James Bond. The movie manages to be a spoof and serious at the same time. Although religion is definitely the butt of more than a few jokes, the movie makes it clear that ideas about faith are good to have.
