This movie is the measuring stick for which I rate all other Shaw Brothers films. I remember seeing this movie on Black Belt Theather in the 80's when I was young and LOVING it. The 5 element ninjas are the most interesting characters I've come across in any martial arts film. The kung fu in this film (as in just about any other SB film) is outstanding. I love the training sequence that Chang Yin Tee goes through when he learns the secrets of the ninja. The movie is just an excellent all around showing of weapons combat.

[9.8/10]
