I don't usually give 5 stars to a movie, but 4 stars would be too little. I wasn't expecting to see so much quality in a not so well know animation. It takes the very hard task of dealing with bullying, suicide and friendship through the specific points of view of its very complex and human characters. Even in two hours of screen this is a very difficult task and I was in awe when I saw that they've made it. It's not perfect, but it accomplishes its goal magnificently, without recurring to clichés or letting things unexplained. The use of different resources to transmit its messages was also very impressive. Everything is well tied up and it holds you watching, a must see.
