Gripping storyline, moving very slowly but a great climax. The relentless determination of the police man gives his final behavior enough explanation. Strong acting. Beautiful, contrasting imagery with flowers and nature to oppose the rotten minds of the good and the bad guys.
The scene at Harumi's place where he makes her wear the "bad" dress is also very telling. There is a certain confinement to the camera in this films which the later films don't seem to have, but it works very well here.
Some fantastic photography from the underground, dancers and many other scenes.
