We like it also. Here's my 2 cents/theory...
I think the lack of popularity among the locals is that they were hoping for something like
Disneyland and then got DCA. The folks who tend to love DL out here (local citizens, as opposed to enthusiasts) have never really experienced the variety that comes from going to the 4 parks of WDW. When they are given the "setting" or background, it's not over the top obvious what things are supposed to represent.
For instance, the 3 themed sections - Hollywood, the Golden State, and Paradise Pier. The backstory on what these mean isn't immediately obvious (except for Hollywood). When you say that you are in the Golden State section - you have a mish-mash of all the things that make CA popular - the woods and natural resources, it's agriculture, the unique city of San Francisco and it's Pacific Wharfs. To the uneducated - these areas are very separate from each other - they don't see the tie that binds.
The same goes with Paradise Pier. So many of the pier amusement parks are gone. Therefore - all it looks like it just an excuse to do a traditional theme park.
I think that's what folks don't get. They wanted more Disney, not something that they had to think about the theming. I could go on about how they really need a weanie attraction to take folks back to the Monsters Inc area to increase activity, but that's another discussion.
Like I said, we get it - and we like it. We'll still like it when the next phase is completed.
But I still won't go on the Spinning Mickey Wheel of Death....
