Tsukamoto one day said "fuck it" and decided to amp up his game of "rage" that he had previously perfected with Tetsuo (and later Bullet Ballet) into a "boxing" film. Said "rage" is amplified by like 99999999999x more with Ishikawa's score (rest in peace).
I swear, those two were DESTINED to work together. They're like bread and butter.
This is, as I said, rage filmified. Those invasive camera angles, the inclusion of body horror into a boxing movie, repressed sexual feelings, crazy ass training montages that have geniuine anger put into them. Tsukamoto really is a guy that knows how to shoot aggressiveness in the camera.
I fucking love you guys (as in both Tsukamoto and Ishikawa). No homo tho. Oh and yeah this is my 666th which is quite fitting (or should I say I picked this up knowing it was going to be my 666th movie).
