Basically the movie is about people being beaten up by Muay Thai.
So-so plot and decent cinematography. The story only accompanies the action and the shot does need more work in here and there, especially in action scenes. There seems to be unintentional comedy from the way the plot and cinematography is directed. However the choreography is excellent and Tony Jaa's performance is astounding. Though along the movie the only decent opponent is the boss' right hand man (others are merely cannon fodder).
Devastating Elbows & Knees, awesome!
