It's not quite the standard collection of types -- I missed the little old Jewish man -- but some things are still done the old way. The two black characters die early, and both pretty pointlessly, for instance. I suppose the creators think they're being badass by giving everyone a potential character arc, only to cut some short until we're down to a final two. Problem is, this is the sort of film where you assume that most of the cast will die, and that makes it hard to invest any emotion in any of the characters. A really daring film of this type would be the one where everyone sticks together and a majority actually survive. This film, despite its pretensions to sacrilege, isn't that daring.
Scott Stewart's film does have a few interesting moments. I dug the angel combat, when a swing of a wing can deflect a bullet or rip a belly open. There were a few presumably intentionally funny moments, like when beery diner owner Dennis Quaid challenges Bettany at gunpoint to "show your goddamn teeth!" But it's basically a collection of influences, a movie made of parts of other movies that doesn't quite live. It's not even inspired enough to be truly bad. You may even find it passable company for 90 minutes or so if you're in the mood for a shoot-'em-up with some fantasy thrown in. But you'll probably find it less memorable than its various source materials.
