Unfortunatly, my knowledge of older (pre-Sammo, Jackie, &Yuen) Kung-fu films is somewhat limited, so in reviews of titles such as Shaw Bro's movies, I have very little basis for comparison. That said, I found this to be a great film. The only version I could locate had a horrible dub, but other than that I had nothing to complain about.
A cool opening credit sequence sets the stage, and the first scene is an awesome attention getter. After that things slow down a little, but not much. Humor is used to great effect, particularly in the seen where two assassins attempt to kill the same man, unaware of each others presence. A lot of times humor in Kung-fu movies I find distracting, but it worked nicely here.
Finally, the choreography was excellent. The camerawork was a little sloppy at points, but passable, and a couple of really cool camera shots got in there. If I'd found a subtitled copy I would've liked it even more, naturally. 8/10
