I chanced upon this wonderful film on an international flight. I can say that, after spending more than 50 years in martial arts and seeing many Asian films with unbelievable plots and characters, this is a classic. The Kung Fu is authentic, the plot believable, the characters are real and yet there is enough humor to make this film a must-see. It ranks up there with Drunken Master and Crouching Tiger Hidden Dragon. My only criticism is that the final fight sequence is a bit drawn out. It's difficult to believe that someone could take that sort of punishment and fight on. On the flight the English sub-titles were a bonus to overcome the aircraft noise, but a dubbed English version would be easier to watch and attract a wider audience.
