I'm going to be completely honest with this review. The cast and their acting was spectacular! Ryuya plays an autistic boy so well and it really gives authenticity to the story, Erika is an amazing actress and is so diverse in her acting styles and Kazuki is just perfection. I enjoyed this movie until about halfway and from there the storyline just went downhill. The ending especially disappointed me due to its ambiguity and while it should have made the watcher feel the emotion of the characters, it was very difficult to sympathize with any of the characters which I will attribute to the story writing. The music wasn't all that crash hot and could have been better however, it wasn't terrible. I wouldn't rewatch this movie for the reason that the plotline wasn't all that original. This wasn't a terrible movie and I encourage people to give it a chance ... it just wasn't my cup of tea.
