Most of the stuff WDW "got" was necessary additions after decades of stagnation and neglect in the swamps. They literally stopped building new things and astronomically raised prices while slashing service to try to reduce crowding without affecting spending (Iger's words, not mine). Much of it also replaced things that already existed, instead of being new builds.
Those two new fireworks shows were at the expense of two wildly popular and nearly universally-beloved shows, one of which had only recently premiered. The show at Epcot also came at the expense of the sightlines across the World Showcase Lagoon, as they've filled it with hideous hardware that only serves a purpose during the show at night. It also killed a beautifully orchestrated show about humanity's oneness to force in an IP Disney singalong around the world, with incredibly questionable inclusions considering its stated purpose of cultural relevancy (Arabian Nights and I Wanna Be Like You in 2021? Really? Misguided at best) .
And are we really counting the return of the water pageant as an addition for the 50th? I mean, sure, it got a "new" float, but the fact that one of the main things the poster you were replying to offered as stuff WDW got for the 50th was the return of a very minor attraction kinda says it all. Then there's stuff like KiteTails, which is just... bad in the most hilariously embarrassing way.
All of that is not to even mention that nearly everything WDW wound up getting wasn't even supposed to be for the 50th, most of it was already planned and meant to open before the celebration started (see first paragraph, ie: decades of stagnation).
So, yeah, color me a little bit jealous that Disneyland gets a nighttime parade back when they just let ours sit outside in tents and rot and never replaced it. Comparatively, it just really feels like Disneyland gets the majority of the love when it comes to continuously being updated and maintained. Nothing against any of the Disneylanders here, of course I'm happy that the company once again recognizes the importance of maintaining the crown jewel OG of the Parks, and I'm sure you guys often feel the same way about stuff that you get. It's the downside of loving these spaces, even if I don't really feel like I love them as much as I used to lately. And I really don't mean to sound like one of the "WOE IS ME" WDW people, but I guess it's just hard to watch something you've spent 35 years loving so much slip further and further away from what it should be.
