Oh, this is why I never saw this thread: it was posted while I was on a holiday!!! It's time to revive it, if only with one post more! :D
Go tops my list of favourite Japanese movies. It's rough, at times hard to digest, everything but "beautiful" in the scenery department, but so brilliantly acted and executed it left a very deep impression on me. It also made me think over an issue I knew nothing about, i.e. the surreal situation of half Koreans in Japan.
I am a huge fan of Yosuke Kubozuka and it makes me mad that his accident or whatever it was (don't care), put a halt to his career, because I maintain he's one of the best young actors in the Japanese panorama.
I also wrote a review of this movie, and I remember it's been one of the hardest for me, because the reasons I loved it have a lot to do with the fact that this movie isn't cute at all. It's more like a punch in the stomach.
Love it, love it.
