Hands down the best movie I've ever seen, even considering non-animated titles. Genres: Slice of Life and Drama.

A Silent Voice
The official english title translation is awful. It takes away from the original intent. However, this is the only bad thing anyone can say about the entire animation.
The protagonist, Ishida, starts out as a spontaneous bully child who is eventually struck by how despicable his actions were and starts to resent himself for picking on a deaf girl.

Now in his last year of school, he still isn't able to deal with his past sins, which leads him to become a social shut-in who eventually decides to suicide, but changes his mind at the very last second.
He sets out to meet the person who he had once bullied. At this point, the plot expands into everyone related to his situation with greater depth: his old friends, his family and the bullied person's family.

We get to know everyone's lives who were involved with him since he cast himself out years earlier, and how they deal with each other in the present, along with new acquaintances.
Koe no Katachi presents us with an emotional ride. One you'll feel happy to have watched once it comes to an ending. Throughly recommended to everyone.

Manga
Koe no Katachi was first presented to the world as a highly acclaimed story, but the movie is truly brilliant, so even if you decide to read the manga first, don't miss out on watching it!
