What anime did you find to be the most underrated?

Mine would be Koe no Katachi. The main character is probably the most relatable character I have ever seen, and what is really unique about him is that he is a cruel deaf hating bully who is actually a really deep character. The story is about him meeting back up with the deaf girl he used to bully, and how he tries to make it up to her. It is a beautiful story of friendship, and is in my top five favorite animes. I just found it to be really life changing and touching.
