It may have a cheesy structure, and long segments that only sort of advance character without doing much for the story. However, this is a showcase of craft and history via inspiring demonstrations and a simple framework; many other martial arts and wuxia films evoke what Chang Cheh delivers unadulterated.
A great Chang Cheh film. I was in awe of Lo Meng's monstrous physique. There's plenty of bloody martial arts battles and the lengthiest training sequence I think I've yet to see. Only strike against it is that the ending is rather abrupt and depressing. I felt like there needed to be a sequel even though there was barely anyone left standing.
