OK...first a caveat, then a small rant.
During the course of the following rant, I'm going to cite some relatively specific examples. It does not mean I don't like certain parks. It does not mean I don't like certain rides. It does not mean I hate the globe parks, the mouse parks, or anything else. It's just how I see things...agree or don't.
The thing I like most about WDW is that it's relatively timeless, while still being relatively fresh, during any given visit. You have classics (which should be lovingly maintained and refreshed when appropriate) that almost act as a museum to times gone by, when the grass was greener, a la Norman Rockwell paintings. On top of that, you have more modern attractions that take advantage of the newer tech, cooler whiz bang effects, and (in many cases) more interactive experiences. It's a nice mixture.
My problem is this: I don't want WDW to morph into IOA (see caveat above, FYI). IOA is a great park. WWOHP is, by all accounts, an amazing spectacle with a stupendous piece of tech at it's centerpiece. But I look at that park....and while I have a GREAT time while I'm there....it's not the same. And I don't mean that Disney has more magic, or that it has more "soul". I'm strictly talking about the attractions, themselves. There's not the same sense of "gravitas" when riding those attractions.
And then look around: Jurassic Park? My kids have never seen those movies. Toon Lagoon? Dudley Doright, Betty Boop, and Popeye were approaching the end of their runs on TV when I was young...my kids have never seen them. Marvel is a great property, and Spiderman is an amazing ride...but it's 10+ years old. Ditto on Hulk. And when you rely on tech (like Spidey does) to draw your audience, you eventually get left behind (FJ), and the lines dwindle. It seems like those types of rides lose their luster much quicker than something like HM or POTC does. HM and POTC and IASW....those types of attractions have been drawing crowds for decades and probably will for decades to come. Will Hulk? Will Spidey? The funny part: Suess may have the longest staying power of any of the current IOA properties (HP remains to be seen), given the contracts on the books.
Tech is a fickle mistress. So are "pop culture" and existing media tie ins. They will draw you crowds quicker than ants to a picnic. But when the next great thing pops up across the street (or across town).....the crowds tend to follow (never mind keeping new tech operational to maximize throughput). Until WWOHP arrived, IOA attendance was generously described as static (and numbers had shown it falling in recent years..though because of the economy or the park was always left unspecified). I think THAT'S what you get when you rely on a constant stream of new tech. You see large peaks and DEEP valleys...but that's the audience you're catering to.
WDW has shown remarkable staying power and I don't think anyone can deny that at least PART of that is MK's almost reverence when dealing with many of their classic attractions. They do update and refresh them, but they don't modernize them JUST to modernize them. They don't "tech junkie" those attractions (and they clearly could) because it doesn't make sense to do that. They know their audience.
Again, I go back to the museum comparison:
IOA is a gallery FULL of recent modern art. Some of it is stupendous, with tremendously new techniques, that make you ooh and ah at the results. But...3 months from now, when you go back....you're less impressed. And, eventually, the turn over in that gallery is VERY quick, in order to keep people coming in.
WDW is the Metropolitan or the Louvre. You've got timeless classics hanging right next to modern impressionists (OK, maybe not RIGHT next to, but in the same building). You come back again and again to see the classics AND see what else, new, might have been hung since your last visit.
