Why do you keep baiting criticism for Zootopia? It did steal an Oscar, but it’s obvious I’ve said my piece and, as mentioned, I actually enjoyed that movie.
You answered your own problem. Let’s not pretend Disney will ever release a cartoon where the protagonist — be it human princess or rabbit cop — fails and dies.
But then again, this is basically hero’s journey. I mean, Luke Skywalker, Indy, Batman, Spider-Man, James Bond, etc, etc.
That’s why Moana stands as a classic and will prevail the test of time. If we’re being brutally honest, Zootopia frankly tried too hard to be “hip” and “relevant”, which is the very reason why it risks diminishing returns for every new generation of kids.
