Reviews:

"The final fight scene alone - a one versus thirty or so affair that scales the outer ledges and neon signs of a multi story building and sent at least one stunt man to hospital - is absolutely jaw dropping, an instant classic in the martial arts world and one which is, all on its own, more than worth the price of admission."- Twitch

"The film's climatic showdown definitely cements its place in the annals of cinematic history"- Cinema Suicide
