I finally saw it last night, it's a movie I've wanted to see for quite a while.
It's a quite simple review, really - sheer frustration. Everything the character's did in the movie was the exact opposite of what any sane person would do. Honestly, what the hell? Other than that, it was well realised and certainly looked the part. It was just that there were several times I just wanted to punch that main guy out and drag him out of there.
