Nothing But Glorified Porn
Hello,
First off, let me say that I am a fan of all things Japanese. I speak the language. I also love good movies, and I have absolutely nothing against porn. Unfortunately this movie is neither of those things. It is a string of sex scenes held together by short, MEANINGLESS "dialogue" usually talking about their sex life together. I understand the sex was an important part of the story here, but I think we could get the idea that these two people were in love/obsessed with each other with either "implied" sex scenes, or just a few good ones. We don't need a WHOLE MOVIE of sex scenes to create a "story." As far as that goes, there is literally NONE in this movie, until the last five minutes. It tries to walk a line between "art" and porn, and completely fails miserably at both. If they had made up their mind one way or another, and committed to it, it would've been much better.
The other movie "Sada" which is based on this same event, is so much better as far as ACTUAL story and character development, that once you see it, this movie will be a slap in the face.
