Eh, not only. Some of my favorite Ghibli films are Non-Miyazaki. I mean more generally things like their old-school animation techniques (don't want another Earwig), meaningful storytelling, not chasing current anime trends etc.

I mean, mostly, yeah. And the parts that aren't him are his other friends in a similiar age range. I don't think Ghibli has any young talent of that caliber. A lot of amazing animators, but nobody that would have left a visible impression to continue carrying the torch.

And I am not sure someone else would have the same respect as Miyazaki who can yell at them for not having enough detail in their movement. You take that from a grandmaster of the art, but would you take it from anyone?
