Best watched on a hdtv that will stretch the full frame to appear wide. Some parts get a little too much into American entry of kung fu cinema and the like, basically reminding you what kung fu did for action films and for the world all over. But mostly you will find rare interviews with Sammo Hung, Bruce Lee, and Jimmy Wang Yu...and good clips of classic kung fu flicks, which gives you a good reference to other films to see such as The Victim, Chinese Boxer, Fists of Fury, Legend of Drunken Master, 5 Fingers of Death...and more also including other revenge films of more modern times, Hard Boiled and The Club.
If you like Kung Fu movies, this documentary is for you. Filled with interviews from Wang Yu, Samo Hung, Yuen Woo Ping and Bruce Lee, it gives some insight into the some of their greatest movies. If you are not interested in this genre, you may not like it, but then you wouldn't be reading my review either.
