This should be reiterated:
its a B movie about Jesus fighting vampires to save lesbians.
It's a really great movie, but I do have to admit it goes downhill big time after Jesus cuts his hair and the end of the musical number. Check it out, though. If you can appreciate B movies in general, you'll LOVE this one. If you totally hate B movies, you'll probably still get a kick out of parts of it, but it may not be the best thing ever for you.
