In my case is more appropriate to ask how many anime series I haven't seen than how many I have seen
I have watched many series of various genres and there is one thing I can say for sure
There are no other series of the romance, drama, comedy genres that can have such an impact on the emotions of the viewer..
A Work of art that alternates joy and sadness within its brilliant story and characters like no other series of this kind.
Truly a MASTERPIECE
