First of all, if you are squeamish (even a little) DO NOT watch this movie. But if you've got the stomach for an extremely violent (and sometimes depressing) movie this might be worth your time.
Vince Vaughn does an excellent job. In fact, the acting in the whole movie is surprisingly good for a grindhouse-style flick. This is about a man in a bad, bad position, who bad things happen to, and who in turn does some very bad things. But if you can handle this type of movie you will be entertained.
The action is gritty to the point of being potentially sickening. I was disturbed, and yet I wish more movies took this approach to action. The fight scenes are not comic bookish like so many movies, rather they are brutal and somehow realistic. Honestly they were the best thing about this movie.
Don't expect a brawl in the sense that a whole cell block starts fighting riot style. This is more of a Bronson-esque "one man out for revenge" style of movie.
The only negative I noticed is that there were a few unbelievable parts regarding the prison system, but they were needed to drive the plot along in the direction it went. Viewers should really just suppress their disbelief (and gag reflexes) and just strap themselves in for the ride.
Recommended for anyone that can handle the darkness and appreciate the brutally gritty craziness that is this movie.
