There were, of course, other good manga and anime.
As for anime, I’m finding that I prefer finished stories where we are not waiting for another season that might or might not come. Of course only if they have a proper, well-fitting ending.
It just happens too easily that something is off to a great start and then falls down, either because the writer is unwilling or unable to wrap it up properly, or because it is wrapped up too quickly, or just in a bad way.
Strangely, I don’t have as much of an internal barrier when nominating unfinished manga. Maybe it’s just the difference that most anime “end” when the story is not finished, while Manga are just ongoing continuously.
