Okay, so The Lion King doesn't fit in Animal Kingdom because the plot doesn't have to do with Animal Kingdom's themes, or because it would stick out like a sore thumb in the more realistic Africa.
But when we point out that Indiana Jones and Encanto don't fit in Animal Kingdom because they're not about animals or nature, we get bombarded with "Oh, well, they could use the characters to tell new stories that fit!" - nor does anybody seem to have a problem with the animated Encanto characters and house sticking out like a sore thumb next to the otherwise realistic "Tropical Americas" land (and that's assuming the land isn't just Indiana Jones and Encanto Land).
Heck, what about the also animated Moana, which people claim would also be a perfect fit for Animal Kingdom?
