That would make too much sense.
Zootopia is not a movie about animals, it is a movie about social issues that simply uses animals as a cute, creative, and child-friendly storytelling device. Epcot is centered around the progress of humanity and the value of diversity more so than any other park. Rarely do I find myself agreeing with JT but here I do. It’s not a perfect fit but it’s a better fit than in any of the other three parks.
I'm quite familiar with the underlying themes of Zootopia, but thanks for the refresher? Zootopia has nothing to do with the progress and achievements of humanity and our relationship to the natural world. It's an allegory about accepting differences using animals instead of humans. I don't really see how it fits at all.
