As others have mentioned, this is a solid film about corruption among feudal samurai. The acting and cinematography are both good and the evolution in the characters throughout the film is solid. The action scenes, while not all too common, are very frenetic and gripping.
It is easy to see why this was a Criterion release. There are certainly a number of good samurai movies, but this one isn't like all the others. The title may easily be confused in English with "Sword of Doom" and the protagonist does look quite a bit like Tatsuya Nakadai, but these movies and their themes are completely different.
The movie also stayed with me after watching it. It left me thinking about cults, fraternities and clans. Individuals who dedicate themselves most selflessly to a cause or group, aren't they the easiest group members to sacrifice?
