Can’t blame the fighters for starting out a bit slow, since they were probably freezing. The action gets good for two minutes beginning at 0:39, with competitive action on the ground and a change of dominance. After that, they were mostly just standing and holding each other‘s arms. Seems the sound track is out of synch. We hear punches right from the beginning before we see any, and the sound of scuffling when they start throwing punches. Then there\'s no sound for the last minute.
