I don't like "grade inflation" but I just had to give this a 10. I can't think of anything I didn't like about it. I saw it last night and woke up today thinking about it. I'm sure that the Hollywood remake that someone told me about, with J Lo and Richard Gear, will be excellent, but this original Japanese version from 1996 was so emotional and thought-provoking for me that I am hard-pressed to think of any way that it could be improved, or its setting changed to a different culture.
A story I found worth watching, and with o fist-fight scenes or guns going off or anything of the sort! Imagine that!
All the characters seemed well-developed, ... even non-primary characters had good character-development and enjoyable acting, and the casting seemed very appropriate.
It's always hard to find a good movie-musical in our day and age, and perhaps this doesn't quite qualify (there is plenty of learning how to dance, but no singing) but I really think that Gene Kelly and others who championed a place for dance in our lives would have thought so very highly of this film and the role of dance in helping to tell a story about a middle aged man, successful with a family in Japan, looking for something... he knows not precisely what.
To the team of people in Japan who contributed to this film, thank you for creating and doing it.
