Favorite Anime? Why is it?

What is your favorite anime to this date and why?
Mine is Koe no Katachi (A Silent Voice)
It is my favorite because of the beautiful story that shows the life of a bully and how hard to worked to get forgiveness.

The art style is amazing and the soundtrack as well even though it's only a couple of notes on a piano for most of it. It adds to the tension and feelings you're going through at different points in the anime. I think that music plays a huge part of anime and there is a right time for there to be music and a wrong time and I think that this anime pulls it off really well.
