Japanese director Takashi Miike has made some enjoyable extremely violent films that I've enjoyed like FUDOH and ICHI THE KILLER and then there are the weird films(VISITOR Q for one) that I found interesting even though they seem pretty pointless beyond just being weird. A film reminiscing about youth in Japan with tumultuous relationships is probably not exactly what I would want to see from him. It is mixed with the usual hyper-violence so things don't fall too much into the romantic chick flick mode but still one of my least favorite Miike films so far.
There was a follow-up to this called YOUNG THUGS: NOSTALGIA the following year, which is actually a prequel, but I'm in no hurry to see that one. There's also s 1996 film titled BOYS BE AMBITIOUS which is supposed to be part one except it takes place in the 70s and wasn't helmed by Miike.
