I felt that way for a few anime; unfortunately due to the lackluster ending of Naruto, I was more pissed than sad.
Naruto is probably one of the worst animes I've ever watched lmao
This thread belongs in the M.A.C section.
OT:
The only anime series that got strong reactions from me at it's ending were Code Geass and Mirai Nikki. Mirai Nikki was touching (if you watched the OVA), while Code Geass's was bittersweet.
Code geass had one of the best endings imo.
