i think we just want to hold the company that invented the "theme park" to those same high standards......
A shame really as you'd think they would want their largest and by far most visited resort to be the best. With four parks it still somehow seems to be worse than Disneyland, Tokyo Disneyland, and comparing just MK to Disneyland Parc Paris.
I think the main issue is their treatment of Walt Disney World, as the additions to Disneyland, Hong Kong, (although not theirs) Tokyo, the new Shanghai, and to a lesser degree DLP actually have added updates to their parks.
Disneyland Parc Paris has the unique situation of the park underperforming, so they couldn't really afford to add a big headliner to the castle park this decade.
Meanwhile WDW is breaking records practically everyday yet the
last major ride added to The Magic Kingdom was Splash Mountain. At Disneyland Paris, the park itself was only open for 3 months before they made the last E-ticket added to MK which was Splash Mountain and on top of that we lost 20k Leagues Under The Sea. And the only major ride update MK has received was the Haunted Mansion, but Disneyland still found a way to upgrade it. In the time MK has topped 20 million in a year's attendance (thus the guest experience going down with higher prices) Disneyland has overhauled Space Mountain, The Haunted Mansion, Peter Pan, Alice in Wonderland, Matterhorn, Big Thunder, Star Tours among others... added Indiana Jones Adventure, added a great Toontown -- may I go on?
Partly to blame for this was EuroDisneyland's unfortunate failure which caused the already underfunded 2nd, 3rd, and 4th WDW parks to cancel, shrink, or delay expansions to the second parks at Disney World which is chasing them to expand now. But today the problem for the MK is that too many people go so there's no reason to add a spectacular new attraction, even for capacity. Which is actually quite sad as we are still in a deficit of attractions from the last century for the MK.
Thankfully they are fixing the non-castle WDW parks now, but as much as I love Disney and if you have been many times, the MK is really only worth more than one visit per trip if you can go super early or late in the day, or off-season times. I mean you can't even get on Winnie the Pooh without waiting over half an hour.
