First of all, this movie is underrated and honestly, I think this is one of the most depressing movie of all time. Even in the form of anime, the film delivers the story in such a heartbreaking way. It is really dark and the character development is great. The movie delivers the character's emotion to the viewers with marvelous precision while greatly controling the pace or tempo of the story with calm backsound. This movie surely will drive the viewers emotion heavily and intensly. In the end, my mind said "what a superbly touching movie..!"
