Movies about angels and ragnarokk and such often are quite good; so on the basis of that I just wasted 90 minutes watching one of the worst movies I've seen in quite a long time.
The short of it is DO NOT WATCH. It is a horror/zombie/apocalypse flick that just can't do any of those things. Its not even scary. Sometimes it's so bad you laugh, but it not really even bad enough to be really funny either.
