I wouldn’t say ours is in bad shape. Buzz and COP are getting big upgrades, Peoplemover, AO, TRON are great. Space mt would hopefully be next after BTM reopens. Speedway, MILF and empty SGE are the biggest issues and even the LF is still a decent show.
WDW's certainly not bad (and (no pun intended) lightyears better than Disneyland's (except Space Mountains)), but, as
@HMF elaborates in his articles (& other echoed elsewhere), it's become so challenging for Tomorrowland, as a whole, to WOW!
1955 DL, 1971 WDW, & 1998 DL
did not wow.
1967 Disneyland TL wowed (& I just learned how
heavily Walt's influence was on it...although he didn't see the final result)
1975 WDW TL wowed
1994/5 WDW TL wowed
But, even in these instances, by nature of the land, the wow wore off.
That's why (at least in-part)
Paris did Discoveryland instead
Tokyo replaced most of their Tomorrowland with a Fantasyland expansion
EPCOT (OF TOMORROW for cyrin' out loud) jettisoned the concept of "Future World" altogether.
I don't mean to keep repeating myself, but I'm really "hopin' against hope" the 26 Dexpo will finally (& seriously) address the US "Tomorrowlands"
NB: I do see how all the changes in Frontierland may ultimately result in a name-replacement there. At this stage I don't care. It's pretty neutered as it is.
