Kokoro is a dark, cruel drama which I found as a non-Japanese difficult to appreciate totally. Maybe it is difficult for a Japanese too. Certainly it is an extremely powerful film, beautifully acted and well-worth seeing. It is the sort of movie that I will want to see again and again, though it is not light viewing. Ibsen comes to early twentieth century Japan. Highly recommended if you are not prone to depression.
