This movie is, however, a good solid action movie. 5 martial artists make the cut to join to US team, and face Korea in a tournament.
After various and sundry fights, the tournament happens.
There, there is various punching and kicking, and a lesson for everyone in the end.
The major difference between this and most other action movies is that it's done very well. Each of the main characters appears to be a competent martial artist - Phillip Rhee especially. The fight scenes are very well choreographed, and about as realistic as these sorts of scenes can get.
Chris Penn is amusing playing about the character you'd expect a Penn to play - brash and tempermental.
Overall, I'd recommend it for the fight scenes. If you can fast forward through the 'plot', you'll be much happier.
