I really liked this movie a great deal. The fighting, acting, and direction were all very well done, although I would've dug a more complex story. It was bad as hell to see Donnie Yen play Wong Kai-Ying, he gave the character the appropriate level of stoic badassness so lacking in the typical portrayel of him ( Drunken Master or Challenge of the Masters, for example) People tend to forget that he was one of the "10 Tigers of Canton", and as as such was as formidable as his son, if not more so.
Yuen proves himself more than worthy behind the camera, with some neat pacing techniques and good use of humor. Another positive aspect was that this film could pass for being made in the last few years as opposed to a decade ago, unlike so many early 90's HK flicks. It is slick in look and well-choreographed, to say nothing of the magnificently orchestrated final fight sequence. 10/10
