I'd give this movie 8/10. I've only seen a few of Jet Li's movies but this is the best one to date after 'Hitman'. His performance is good, he does what he can with some corny lines, and the fight scenes still impress me (because I haven't seen many films that fit so many in!).
The only gripe I have is that because I'm waiting for my DVD from Amazon I had to watch this the first time in odly dubbed English/New Zealand (?) voices - not the way to go!
Rent it - enjoy it! A good way to waste ninety minutes.
