This one - like The Land of Hope, for example - is a difficult one. Why? Because if it was from the hands of some famous Chinese, Japanese and mainly Korean directors, it would be praised as a masterpiece, but as it comes from Sono, it's different from what people expect and divide opinions.
It's a fantastic film, a great exercise of growing up with all the adversities against you, showing us how dysfunctional families can affect our future, even if we have dreams and want to fight for your dreams - this affects both of the main characters, but we also see how each of them react differently to different circumstances, just like in real life.
I expected that, by now, most people should have already know that there isn't a single Sion Sono. I am lucky to love all of them. To love the crazy Sono (who reminds sometimes Miike, but funnier and more consistent) and love the introspective Sono (sharing a lot with the Korean new wave, or even with some Chinese and Japanese dramas from the 80s/90s). But if you just love the crazy Sono, you should know that this other Sono is not for you. You can't be expecting the same on this type of movies.
I will mention again The Land of Hope to explore how Sono, one more time, can show us not only the family drama, but also, at the same time, criticise some aspects of the Japanese society, as, per example, how the society treats the people who lost everything (there is a great subplot about this with a fantastic interpretation by the veteran Tetsu Watanabe) or how schools can be cruel to a lot of young people.
Overall, I am one of the few who, in fact, prefers The Land of Hope - the balance between the elderly couple, the land, and the young couples was perfect, for me - but I think that Himizu should be much more praised than it is.
