I liked it, Jackie Chan was fantastic, he keeps getting better and better at making american movies.
Jet Li somehow forgot how to speak english since his last american movie, he just sort of vomits engrish out in dry heaves. It was very hard to understand him. They should have really gave him a silent role.
The Jackie Chan vs. Jet Li fight scene was fan-fucking-tastic. I will rewatch this movie many many times just for that fight scene.
The white kid angle was totally unnecessary, only put in there to give the American audience something to relate to. If this was a chinese movie with a chinese kid in it instead of some white kid it would have made this movie an instant classic kung fu movie.
The romantic interest chick was great. Dont know who she is but good acting and good fighting, she might have a real future in movies as the "asian chick".
All in all Jackie Chan really shines in this one, and as a big fan of his its easy for me to like this movie because of that.
