The violence was really uncomfortable to watch & it is nearly impossible to empathise with any of the characters. I think that was the intended point according to reviews I've read but not sure of the purpose for this. Also I read that it was supposed to comment on Japanese society but unsure what exactly said commentary may be! Maybe the odd glimpse during the shopping district fight scene regarding the voyeuristic nature of society or the overall disparity of youth. But even so; I'm really unsure if that is it or as to what else it may be. There's no reason given for any of the characters motivations either. I'm guessing Suda's character is just chaos in general & to feel superior, but why? Nothing is even hinted as to why he's so unsatisfied & the same applies to Taira, he's just someone who beats on anyone he can. Because? Well we never actually find out. Nana's character is just sort of dragged into things; but she's not likeable either & again we barely discover anything about her. Basically it's just a movie with violence for no rhyme or reason! Acting seemed good with everyone putting their all into their respective roles; even Komatsu Nana which I find questionable at the best of times. But besides that, there's absolutely zero I could take from this other than the feeling like I wasted my time! I found this to be an extremely uncomfortable & headache-inducing viewing experience! I especially had trouble with the score/soundtrack. It is frenetic & an assault on the ears but I feel like it suits the intended style of the movie so it has that going for it! Watch at your own risk.
