A lot of good things about it, and a few great moments. Kurt Angle as Fedor was actually really good and needless to say, Nick Nolte was on his game.
I could have done without frequent reaction shots from the Tapout Crew during the fights. It's like this serious movie still somehow felt beholden to the SpikeTV influence. And Kevin Dunn is a good actor, often even in terrible movies like Transformers 2, but the "principal secretly into MMA" angle was a bit much in the corny way it was executed.
These are pretty minor complaints though. It's close to as good as an MMA movie is ever going to be.
