I'm not going to review it any deeper than that, because I want you to see it (except for you, delilahbowie). A truly visceral film. There were lots of things I loved about it, but I don't want to spoil anything.
I'll say this, though: there have been people saying that the acting was bad, especially Carey Elwes. I disagree. I bought everyone's performance. Hell, I even bought Danny Glover, and I normally don't think much of him. The other point that I'll say in the film's defense is that it didn't fall for a lot of the "Hollywood clichés", which rocked. Just a damn good film, in my opinion.
I'll be buying it as soon as it comes out, probably pre-ordering it.
