I completely see your point, but remember Disney controls the IP... they can create custom stories, situations and locales exclusively for the parks much in the way they did with Star Tours, SW Land and the new Iron Man attraction in Hong Kong.
I liked the idea of DCA's postcard entrance and mashup of California architectural styles and landmarks, but man, in retrospect the entry into the park was terrible, especially from that view. Talk about not delivering on customer expectations!
On a side note, as a San Franciscan I found Disney's representation of the Golden Gate Bridge especially cringe inducing.
It's much better now, I agree.
