True, but nothing was changed. They never updated any part of that ride. They could've refreshed the space scene by changing the style of station used, reworked the science lab on the station to have multiple "projects" happening instead of a single spinning crystal, updated the AAs, do
something. SSE, while it feels old, it's still received a fair bit of love over the years for better (the computer room) or for worse (the ending/losing the space station). "Small" scene changes can bring a ride the attention it deserves. Epcot's been abused and it shows. MK gets love somewhat regularly at least.
Refreshing or slightly changing a ride can draw people back to it. If they rode a 45 minute ride once, why should they do it again if they didn't care about it the first time? But if they brought in a new script with new actors, new effects, and a modified story, they'd probably be willing to try it again.
And not everything had to be educational. Those couple you name were great examples of having fun with the subject of the pavilion they were in.
Disney is to blame because they just didn't respond to public opinion at all. The parks have been largely stagnant for the past decade (thanks MyMagic+!) and it shows. SM is in bad shape, BTM still lacks the 3rd lift effects rendering it the same to its riders, Stitch is dead space that literally lowers the parks score when it's open, Imagination hasn't been touched in 17 years and it even has some of the lowest scores on property, the Seas pavilion is still 1980's aesthetically, WoL is dead (currently), the Innoventions buildings are some giant empty building with bathrooms, and ToT hasn't had random drop profiles for a while. Okay, the Yeti also. These are just a few issues in the parks.
I used to tell people "I go every year because something new is there". A couple of friends would ask me what's changed and the past couple years I've been stuck, simply because not much has changed (well, with TSL, SWGE, Rat, and whatever else, I finally can...soon). NFL was
something... and not in a good way but Avatar is
truly something worth mentioning, finally!

@marni1971. Wasn't 1987 the peak?
