Here's a geography blog with an entry on doing just that for It's a Small World. It's a bit long and tends a bit too much toward making fun of the strange colors and caricatures in the ride, which is like criticizing The Very Hungry Caterpillar for the fact that a caterpillar probably wouldn't be able to eat so much on Saturday. There's a lot more to think about with what the stereotypes are doing, and the all-white finale (and the not-so-subtle insertion of classic Disney characters into the mix). Still, it's a step in a very interesting direction. Some day I'd love to teach a class on Theme Park Studies where we do things like this.
And, by the way, all those Saturday morning cartoons and Pokemon shows have a big effect on a lot of people (and not just Herman Cain). I'd argue that you understand more about people by studying these than other less-read and less-experienced works.
