I guess my question is, why have a Ghibli if you don't have Miyazaki (not just a Miyazaki, mind you)? And it seems rather unfair to expect him to keep pumping out films till the day he dies. I mean, he's almost 70 years old. We're talking about a small number of potential films to go, and I didn't really like Ponyo all that much. What I'm saying is, it's got to stop sometime, dude's had a full career, could probably enjoy a retirement.
And what's this about a Porco Rosso sequel? That best be some conceptual, not-actually-a-continuation-of-the-story shit. That movie is a gem, possibly the most perfectly crafted film Ghibli's made; call me a crank, but adding to it or trying to remake it seems to me unequivocally to be a mistake.
