I watched the Hong Kong DVD release of this film - still available, I believe - which offers reasonable quality, though the Japanese characters have been given Chinese names and the English subtitles are sometimes poor. I thought the first half of the film was intriguing, outlandish, imaginative and weirdly funny. The introduction of a rather irritating DJ character added little to the movie, other than an obligatory romantic interest for the anti-hero. As other reviewers have pointed out, the film goes on too long, offering a succession of action set-pieces that seem at odds with earlier scenes. The main character's motivations remain a mystery and the downbeat ending falls a little flat, given the subject matter. For all these faults, I'd give it another look, but what could have been a great movie slipped away somehow.
