Akira Kurosawa’s 1965 film stars Yuzo Kayama as an impetuous young doctor coming into conflict with his aging superior in an impoverished clinic in early 19th-century Japan. As the older doctor, Toshiro Mifune is superb; and though the film has been criticized for its excessive sentimentality by some, it’s a masterful evocation of period and a probing study of the conflict between responsibility and idealism. A mature work that merits the term most apply to it: Dostoyevskian. In Japanese with subtitles.
