I enjoyed it last weekend (mild spoiler)
Really liked the bitterness in the protagonist. Satan was cool and demented. Liked the story pretty much. Effects were entertaining. Demon design was cool.
The ending seemed to stretch on for a very long time. Thought it was gratuitous to off every single peripheral character, like that. And what were those Mexicans doing in the beginning of the movie. They looked like the protohumans in 2001, combing the dirt for treasures?
I will be willing to see it again in less than 5 years (high praise, from me).
