Executioners From Shaolin (1977)
I guess this is considered a classic, but I thought it was just pretty good. The story was a bit perfunctory, and didn't carry much emotional impact for me - plus Wong Yu was annoying (and looked like a girl). The ending was very anticlimactic - in fact, nothing in the film managed to live up to the superb opening scene with Gordon Liu. Lo Lieh as Pai Mei was a great character though.
I'm sure the martial arts were very authentic and the hard core kung-fu fans will cream themselves over that fact, but I didn't think the styles on display were particularly exciting to watch or aesthetically pleasing. So there! From what I remember, the Lo Lieh-directed remake Clan Of The White Lotus was better, but it was one of the first Shaws films I saw so maybe I'll say different when the Celestial remaster eventually comes out.
