I'd argue that Stitch ought to go.
Captain EO was pretty bad, too. Thankfully it's gone but, from what I understand, it was replaced with Pixar trailers.
I think that there are two overall problems that have been going on for so long that they just seem to be accepted:
1) putting things where they don't belong (Dinorama in a Disney park - I know there's a veiled attempt to explain it with the surrounding theme, Pandora, Buzz Lightyear, Stitch, Monster's Laugh Floor, Frozen, etc.)
2) Budget cuts on long-term rides (Kali, 7DMT, etc.) / retreading rides (Buzz, Nemo)
The first one annoys people, myself included, because we'd like to see things properly placed to fit the theme of the area. If you're not trying to fit the theme of the area then the theme of the area no longer means anything and it all kind of unravels.
The second one sucks because of short-sighted budget cuts you get a cheapened or shortened ride which may have very well been an excellent ride. Bluto's Bildge Rat Barge (I think that's the name) over at UNI is what we should have at DAK. Instead, DAK has one of the shortest raft rides I know of - this is for a premium park. The same problem happened at 7DMT where they gimped the ride for budget reasons and now we're just stuck with it. The bottom line looked better for one quarter but we'll have a gimped 7DMT for many, many generations to come (we'll all be dead before it's replaced / changed out). Dinorama looks like another budget cut as does not finishing the fantasy section of DAK (became Camp Minnie Mickey and now will be Pandora).. as does not finishing Tomorrowland. It sucks. It sucks that some suit wanted a better bottom line so you get 1/2 attractions or crappy sections of parks and they don't go away.
Then you have the retreads and while some are better than others, they're still below par. Buzz is fun when it works (another problem) but it feels below par as does Nemo which just feels stuck in the Living Seas. They seemed to do well with Frozen, though, it just suffers from point #1 above.
I get the budget - you can't go bankrupt building a coaster but TWDC could have stuck with the original vision of 7DMT and not left people constantly thinking, "That was it??" when they got off. You get a similar feeling from Kali. You don't get that feeling from Space Mountain, Splash, or BTMRR. They all feel like complete rides.
