Joseph Kahn’s "Bodied" has been dubbed a 'battle-rap comedy,' and it does start that way with the main character explaining to his girlfriend the gist of free-stylin'. If you've seen "8 Mile," you know how it works. You square off against an opponent, circled by a crowd of enthusiasts, in a freestyle battle, just two people in a ring and a war of rhythmical words. What can occur in such a battle is an apocalyptic-like sensation that has an ADD intensity and a cause/effect of whiplash.
