Jacob Olsen’s review:
An amusing film.
Lovely dialogue, the script written by Koreeda himself has more snappy and humorous lines than any other samurai film I've visited. Quite a few of the background characters are also entertaining. Still this shouldn't be considered as a comedy, it's a black one at best. There are a serious undertone of revenge here, although the protagonist is a naive and clumsy samurai his intentions are very firm - he shall kill the man that caused his father's death.
The film weaves the above nicely together with, at least as a gesture, the story of the 47 ronin. No wait, according to Koreeda it was 46 and the one that got away. ;)
PS The choice of music was unusual. I'm not sure what it was, certainly nothing Japanese, was it an Irish reel?
