The immediate reaction after seeing this was that it was good. However the more I thought about it later, the more I'm convinced that it was really great.
Its a little hard to nail down a theme/genre, part social commentary, part crime thriller perhaps. Its set in 60s Japan, where rich shoe maker, faces some opposition to his work ethic. As he digs in his heels, and his son is kidnapped, we see rapidly shifting scenarios, and the movie just jolts you out from any set ideas you would begin to have. There are quick turns, not so much in the turn of events, ( although there are those), but also in your perception of the situations, which keeps the movie engrossing.
All in all, a pretty rewarding movie. Leaves you with much to mull over, long after its over.
