I watched this movie more than 2 years ago.
The reason why I suddenly feel the need to write a review is because I believe it has been wronged in more than one respect. First, the badly written synopsis which focuses on irrelevant details and gives the impression this were a depraved movie of some sort - which is not.
Second, because I have a very hard time understanding why anyone should watch a movie well knowing it deals with incest and then complain about the fact that it portrays such a delicate and offending issue. It's like eating at a sushi bar and then refusing to pay because one doesn't like raw fish.

The main theme of this movie is two biological siblings loving each other. This is not a spoiler, as it is clearly stated in the synopsis. If you think you can't face the issue and are disgusted by the idea, I suggest you simply don't watch it.
On the other hand, if you can confront the matter of an adolescent being obsessed with his sister, this movie deals with it in a delicate, far from vulgar way. It is very well acted and stresses upon the internal - we may call it infernal too - struggle of the male lead to overcome his obsession.
It's a slow film which doesn't play on events as much as it tries to depict the battle between reason and passion. It is not a romantic movie by any means either, and yet there's a sweetness surrounding some of the scenes which goes beyond the mere issue of this being a wrong sort of love.

I can't remember the music, hence the non-committal mark.

Among all the movies I like to rewatch, this is certainly not on the top of my list. However, it is a brave movie which I believe deserves at least some fair mentioning.

This movie has got very specific climate. When I'd read the tittle the first time, I was convinced that this story tells about jealousy overprotective brother towards younger sister. I've been surpriced since I read a short decription. Japan doesn't afraid of taking controversial subjects, and that's why I like its.

Actually, the movie seems like calm relation, but it's good story. I suppose I will watch it again someday.
