Have you been to Carsland yet Steve?"Carsland" doesn't feel like traditional Disney to some of us because it's a land based entirely off a cartoon. Sure, perhaps a good cartoon, with lots of "heart." And sure, the land may feature excellent detailing and theming. This isn't the argument. All agree it looks awesome. In the end, though, it's still a cartoon land.
What land in Walt's original Disneyland was based entirely on a cartoon? Even Fantasyland wasn't based on a single cartoon, and later received theming based on traditional Eurpoean half-timber and Tyrolean architecture, lending the facades of the rides a veneer of reality.
THIS is the difference. Original Disneyland gave us lands based on reality--history, "hard facts," Main Streets and Frontiers. Sure, some of the attractions were based on cartoons, and later live-action movies, but the four overriding realms of the imagination were represented by quasi-realistic themed lands.
