I've seen Tsukamoto's Tetsuo films but here he has found a way to be almost as outre but infinitely more accessible and coherent. The film is about 3 people (two men and a woman caught in a triangle) whose lives suddenly become charged with transformative psychosexual and psychoviolent energies revolving around the world of Japanese boxing (but it is nothing like a 'fight' film). Actor/Editor/Cinematographer/Director Tsukamoto has found a way to give a high impact, extremely rhythmic (in both time and space) look and feel to his ideas that is very original and striking. The spatial rhythm of the lead characters boring ordinary 'day' life passed in high rise apartment complexes and the incredibly kinetic temporal rhythm of his alternate 'night' life provides a terrific cinematic contrast of these two worlds. The film is rather short and gains immensely thereby in both concentration and focus. I, too, thought about Raging Bull at times but probably Tsukamoto is more akin to David Cronenberg (the new flesh) in his concerns, not his approach, than Scorsese. It may not be for the squeamish, but it is strong, brilliant film making which you should definitely try.
