I'm not disputing that Eisner wasn't a good CEO, at least at first. And I actually do get why people have warmer feelings about him these days especially considering that he did craft a public persona that was affable, a lot like Walt did. But, while I wasn't really hanging around specifically Disney Parks fora during the latter days of his reign, I can remember very clearly the general entertainment industry sites were very negative on his management style. And I had a friend who was a former cast member (and just a big fan more broadly) who HAAAAAAATED what he had done to the company by around 2003 or so.
I'm not saying any one person is guilty of this specifically, but I think people's current opinions of Eisner have at least a little to with the same cycle that the Offhand Disney guy talked about in his video.
I mean, it sucks that they made a lot of budget cuts to Toy Story Land and Galaxy's Edge before they opened. But we also have a way of forgetting that Animal Kingdom was about half of the park it should have been when it opened, again because of the budget.
