This movie sorta looks like an MMA (Mixed Martial Arts) movie, but it really isn't, it is about people who happen to being doing some MMA.
Bane plays a Marine who saw too much shit man, in Afghanistan. He has returned home to a father he hates and a brother who he thinks abandoned him, but they all have problems and they need to work shit out.
There are some really fun beatings to watch.
Again, it wasn't terrible. If it was an MMA commercial I would have hated it, but it had about as much fight stuff as the original Rocky, and almost as much angst and lower-income-in-Pennsylvania.
