ITT: Studio's best work
If only there was more development between the characters and their relationships the ending would have been a 11/10 instead of a 10/10.
Second best after SZS
I'd also accept DtB season 1.
So rotoscoped it hurts
Nothing else even comes close.
The movie and the series both.
In terms of KyoAni series, I found that I liked Clannad AS the best.
Movie is definitely Disappearance though.
