If you like watching martial arts movies. This is a definate must see. I believe the fight choreography was done by Sammo Hung, and it is very well done.
The other reviews mention violence. Surely something to avoid showing to children, but by no means did I find it disturbing. Most of the violence is very silly. For the most part, I found them most humorous.
Similar to Shaw Bro.s movie violence. In the first action sequence, the star flies across the screen. It just happens to be convenient that there are about seven soldiers standing in a line, and he beheads them all in one swipe.
The final battle and the tournament fight are excellent. Good mindless fun.
