I personally love this, apart from its being 'not so romantic' according to some criticism. The reason is simply that it is not, and the focus of it is on the actor's psychological side while doing the method acting.
The story was awesome, it has distinct characteristics, they build it so unclear but direct it to the way that people supposed to understand it. Simply, it would make us wonder what happened. The cast's acting, I don't really have a grudge towards it. As it supposed to be, the music is so helpful to construct the scene, I love it, but some of them weirded me out. it might be that I do not really know about musical drama music.

Am I going to rewatch it? yes, when I forgot about the story. But I think, this kinda movie is supposed to watch just once. After you understand the story, the second experience will never be the same.
