Although very different from Tomo Ushida's other late films, with its hand-held cameras, fluid 'noir' cinematography and realistic style, this is one of his unquestioned masterpieces, on a level with any of his post-war work. The acting is superlative - especially from Sachiko Hidari as the cheap and touchingly simple prostitute unexpectedly caught up in somebody else's drama - the narrative is beautifully paced, and the film fully justifies its three hours' length.
Without being one of those Hollywood-style "message" cop-jobs, or anything like Kurosawa's flimsy imitations of same (he is beloved in the States because his films are consciously in their - comparatively limited - transatlantic style) Ushida's film is a compelling thriller, with the inexorable movement of a Greek tragedy such as 'Oedipus'. It is also a deeply absorbing meditation on guilt, retribution, poverty - and most surprisingly, what we might call "the wages of kindness".
This is not some silly procedural for infants, anymore than Sophocles's drama; but it is a great film, for anyone who cares to respect a master of the medium, and gives some thought to what they are watching. (The DVD available from DVDLady is very watchable, taken from an excellent French print, with good English subtitles.)
