I think the extent of Japan's cinematic prowess was sucked dry by Kurosawa and Kobayashi because it seems whatever they've put out since has been terrible degenerate films featuring characters with no redeeming social value. Films like these present the Japanese as savages incapable of rationality. The only good thing about this was the music. Apart from that it was impossible to take seriously...or metaphorically.
