this be indeed the film that popularize kung fu in the 1970s . however and if it ever have any kind of excitement or even halfway interesting plot and it doesn not seem to have age very well . long story short represent extremely draw out and slow moving and confuse plot with run of the mill choreography and typically annoy and exaggerated whiplash sound with every punch and kick and and constant plot twist that never come to an end . by the time the film reach it emotional climax and i have long have all the wind knock out of me to actually care . watch it for it historical value a a milestone of chinese kung fu cinema just leave your expectation at the door and or you will be bitterly disappointed . for hardcore fan only .
