Entertaining, as long as you don't think too hard.

Rating: 6/10 (8 August 2008)

Yes, it's just a revamped Karate Kid.
But with MMA, not just Karate, although I did have the occasional urge to shout "Cobra Kai!" when the bad guy came on screen.
Some cool action, basically just MMA (like in the UFC) that's been "hollywoodized" to be showy, "underground", and performed by supposed teenagers.
Djimon Hounsou is wasted on this film, but does fairly well at being the token real actor, giving it some tenuous legitimacy. On the upside, probably a more believable martial arts instructor than Pat Morita... physically, at least.
It's a great movie to just turn off your brain to, and watch lots of girls in bikinis and guys beating each other up. Pleasant, mindless T&A/Action.
