This sounds like a great film

From io9:

1) It's really wrong. In the best way — at least, if you like movies that go way too far and then just keep going, you'll like this. It has insane ultra-violence, plus some pretty intense and general weirdness. James Gunn, the psychopath who brought Slither, has managed to mash up religion, ultraviolence, fetishism, and a slew of anxieties into one horribly disturbing package. There are some moments in this film that'll stick in your mind for quite some time afterwards.

2) It's scream-out-loud funny. Especially every time Nathan Fillion comes on screen as the Christian superhero, the Holy Avenger, you'll fall out of your seat. There will be Holy Avenger T-shirts everywhere in a couple months, if not sooner. But also, Rainn Wilson is pretty freaking on top of his game as a well-meaning nutcase who really believes that whacking people in the head with a lug wrench will make the world a better place.

The is “Super”. I can't wait.
