I saw this with my kids last night and was surprised to see that they included grappling nearly a dozen times in the choreographed fights. I don't doubt grappling has existed in China for centuries, and not just Shuai Jiao at that, but I have not seen it given much time in movies obviously choreographed by wushu experts until now. I think this is a sign of the changing times that a Kung-Fu movie would include this much grappling at all. By the way, I thought it was a really decent kids movie and Will Smith's son does a good job for a child actor. I also think Jackie Chan did a decent job of acting as well (I like his movies up to rumble in the Bronx but I never would have called him a good actor). It be worth seeing for some.
