'Disney' to many of the mature members of this board does not mean 'cartoon character', or '(aquired) IP'. 'Disney' means a certain take on things, positive, quality.
World Showcase is decidedly 'Disney'. As is Animal Kingdom. And little worlds developed in the parks - Space Mountain, Haunted Mansion.
The idea that Disney means 'cartoon' or 'celeb IP' is mostly new, derived from shortsighted management and guests who either don't know, or don't understand, or can't readily express, what Disney is about.
The 'Hollywood that never was and always will be' as presented in DHS is decidedly Disney. And very successful too. It's a complete triumph of Disney placemaking and storytelling. The imbecile hat detracts from it, makes DHS less Disney!
The MK is not Cartoon Kingdom, with Exotic Cartoons land, Future + Space Cartoons Land, Western Cartoons Land and Strip Mall plus Princess M&G Street.
The MK's magic relies on careful placemaking and thematic integrity. These are at once the most basic and essential ingredients to the magic, and the least understood and most difficult to describe and maintain.
