I struggle to be convinced these two attractions and Ouimet represented a complete 180 by Eisner. Walt Disney Studios Paris, by far the most embarrassing park Disney has ever built, opened just a year before Mission: Space. Hong Kong Disneyland, a Magic Kingdom without any major attractions other than Space Mountain that flopped royally, opened between M:S and Expedition Everest. So, it's very hard to know whether he suddenly "got it" or just greenlit two ambitious attractions during that period when there were still skilled Imagineers around to design them. I still think the responses to DCA's lacklustre opening that also opened around the same time as those two attractions were underwhelming and didn't really address the park's issues.
That, again, still leaves the rest of the company, which was in rough shape. In part because of Eisner was a little Chapek-like in his ability to alienate key people by the end. Even in animation, Disney was very lacklustre by that point. Whatever his faults - and there were many-, it's hard to say that Disney wasn't a far stronger company by the time Iger left than it had been when he took over from Eisner.
