This film is an MMA lover's wet dream. There are plenty of great fights, badass action sequences, and some cool cinematography to make it look even better. It was great to see Michael Biehn in this too, as it's been a while since he's been in anything. He plays a washed up Karate coach who has to train the main character. It was a lot of fun to see him on screen.
Personally I'm not a fan UFC, but I still enjoyed it. I found it to actually be a lot better than it should have been. The script may have been basically written entirely in clichés, and it was predictable beyond belief, however, I couldn't help but enjoy the hell out of it. It's simply a badass film, and for that it's really enjoyable. The action scenes were exciting and tense, the sappy scenes never felt overly sappy, basically I just found it to be a perfectly enjoyable movie. It's basically Batman meets The Karate Kid in story line. The performances are pretty meh, but forgivable, as most of the actors aren't really actors. The editing and camera work are awesome, they compliment the movie perfectly. For a film like this, I actually enjoyed watching it, and for this film's target audience, that's all that's really needed. It's really fun, and has a lot of cool visuals and editing. Just don't go into it overthinking anything. If you love MMA, you'll love this movie.
