Walter Andrade’s review published on Letterboxd:
Ikiru is better in rising questions than in answering it.
Although the idea is interesting, the screenplay soon ends up discussing the theme by a exaggerated cliché about living. We don't know for sure if the central theme is the Japanese system or the art of living. Of course that both things aren't mutually excluding each other, but lack of direction looks a little bit weird. Also, looks like Kurosawa was trying to give a message to Toho Company; apparently it was being hard to get money to make his films at that time.
Technically Kurosawa does not disappoints, but his achievements as a director unfortunately weren't enough to make this film really enjoyable.
