Why is it that movies with Kung Fu elements never really satisfy, except of course for the Matrix and Crouching Tiger. The authors of the story have tried to make a modern day Romeo and Juliet, in this case Asian Jet Li and black Aaliyah. This is all fair and well, but there is no real story to it. They come together, are good and survive in the end.
Thankfully there are some very good Kung Fu scenes by Jet Li which makes it fun. where Jackie Chan is more comedy, Jet Li is certainly art and well choreographed. The scene when he is playing football is a good one, the other is where he beats up some dudes with a hose.
With an hour and 50 minutes it's too long, so just skip to the fighting parts on the DVD.
