"A touch of Zen", the English title is perhaps the only thing about this film that isn't beautifully and subtly conceived... This is a film about about ambition, perception, personality and what evil might be... it isn't really a standard action movie.
The storyline is highly compelling, but not rushed; the pacing is wonderfully handled, moving from the slow, almost lazy quotidian existence of the unambitious, scholarly protagonist to the fast paced, highly dynamic camera work of the action scenes. The shape of the film, perhaps the most amazing aspect of this 'masterpiece', starts with the small (even petty) and slowly ramps through the heroic to the iconic and finally to the divine. Each stage is a brief, often profound meditation on the nature of life and humanity of that state.
The cinematography is always lavish and startling, and, as with many of the Japanese films of the time, not afraid of a screen beautifully composed mostly of shades of darkness.
The martial arts displayed are never exhibitionary nor obviously proficient. This understated quality to the skills is sometimes disappointing (if that is why you are watching the film), but ends up being the best way to capture the the unknowable skills of some of the characters. As a matter of interest, a young Sammo Hung makes an appearance as a bodyguard and there are some other kung fu faces amongst the stunt men.
All in all, this film is profound and compelling. Well worth a watch
