I think the movie was generally pretty good. Good imagery. Not very scary, in the end, though. If you really want to be scared, watch FRAILTY.
Oh, and I know you're new, but we have a books/movies forum. Not only will you find that the mods prefer you take a thread like this over there, but you will also find several already-existing reviews of this very movie. Enjoy.
