First time I saw it on channel 4 late at night, it was being marketed as yet another exercise in Japanese cop/Yakuza violence (and I've talked to a few people before who were put off watching the film for the same reason), which is possibly the worst way of advertising this film I can imagine. Sure. it's full of some quite astonishingly violent sequences, but they are never
ever glorified, and if anything the film is more about Nishi dealing with the guilt of his own violent tendencies and their unfortunate consequences. It's just another example of Hollywood's arrogance that Kitano didn't win an Oscar for it - it's as close to perfect as I can imagine a movie being. Not a single wasted shot, not a single wasted line of dialogue, no patronisation - just an absorbing story littered with incredibly well portrayed characters. Simple and hauntingly beautiful. Hopefully, in time, Kitano will be realised as one of Japan's great filmmakers (better than Kurosawa IMHO). Hana-bi is Kitano's magnum opus, and if he ever tops this film I will be in heaven.
P.S. on reading
IMDB I was also shocked to learn that Kitano also painted all the pictures (which are a major part of the movie BTW) and composed a portion of the score. Is there anything this man can't do?!
P.P.S. Hana-bi is sometimes referred to as Fireworks, but IIRC it literally translates to "fire-flower", which is a kinda double meaning on Kitano's character.
If you consider yourself a fan of cinema, you owe it to yourself to see this film. It's quite simply a work of art.
