I certainly agree that Imagineering as of late has been prone to over-explaining and demystifying certain things that are best left alone.
I do think that DCA over the last 15 years has been pretty consistently following a “celebration of [insert CA thing here] by way of [insert IP here].” Avengers Campus, Pixar Pier, San Fransokyo, and even Cars Land all do this to some extent.
I’m just trying to think of what an Avatar Land would celebrate. The movies? CA Futurism (a kind of Discoveryland West)? CA’s coastline?
