I think this is cool AF. I'm probably biased being half-Japanese and from Japan and I'm no martial artist. And I still think MMA fighters will probably kick these guys' asses, but this seems like a different breed of film. It is beautiful in a way that I haven't seen before. Apparently, some of these fights were no choreographed, just improvised, with lots of injuries in the filmmaking process.Something about it seems badass to me in a way that doesn't seem like the commercialized and homogenized idea of badass, you know. I don't know if these guys can kick ass but it's like there's something to it besides looking cool for the camera.
