This film is disturbing. I say that to mean that this film accomplished what it sets out to. It deals with sensitive issues like bullying, abuse and domestic violence in a nuanced and sympathetic way, without overshadowing the bad things done by both the abusers and their victims. It's also got a twist that works really well in the story. The animation style works really well with the story it is trying to tell. I would recommend it, but make sure you have the right mind for it.
