This is a phenomenally good movie, and is miles beyond 'Hollywood sports movies' in quality, because this one laughs at itself fully, and realizes how over the top it is. I mean, I heard they horribly mangled the movie when they edited it for an 'American' release, but they might have fixed it when they realized how much they screwed it up. But if you see just the one scene when our hero first shows off his soccer skills against a street gang, you'll know how great this movie is.
It's really fun. I saw it in pirated Chinese fansub version, so I'm a bit nervous about the American version, but I plan to go see it.
