One of the reasons Disney was at the mercy of the corporate raiders was that the sum of its parts was greater than the whole. In other words, they weren't utilizing many of their assets. The two I've seen pointed to most were the film library and the real estate at WDW.
So one of two things was going to happen. Either somebody was going to come in and do something with those assets, or they were going to be sold to somebody who would do something with them.
Roy and the Bass Brothers won out, and they brought in Eisner and Wells. No matter who they brought in, they were going to have to come up with strategies for the library and real estate. Its not like Eisner and/or Wells were geniuses for doing it. Everybody knew it had to happen, which is why so many wolves were at the door. It was a slam dunk.
The only question was HOW, and that's where the arguments come in, especially with respect to how WDW was developed.
I really don't get the fascination with making sure Eisner gets credit for this, or doesn't get credit for that. What's the point? The worst of CEO's can still be tied to good things that happened at their company, and conversely the best can still be tied to negative things.
The only real point is the leader as a whole. And in that sense, I truly believe Eisner was the wrong guy from the start. Yes, many good things happened financially for the company during the first 10 years of his tenure. That was a time when he did not have the autocratic authority he later achieved. How much of it was specifically tied to him and him alone? I don't know, but it is telling that as his power grew, and those with power around him left, the results grew more and more spotty, both financially and creatively.
Did he morph from a "good" leader into a "bad" one? I don't know for sure. I do know that based on what we hear from those who have worked with and under him over the years, it doesn't look like he changed his style. It seems it merely became amplified as his power grew.
Its also important to remember that Eisner was brought in primarily to provide some Hollywood clout. Wells was seen as the right business guy for the company. In fact, the preferred arrangement was Wells as CEO with Eisner as President, however, Eisner would not accept that, which is why it was setup so that neither reported to the other.
So does it really matter if I "give him credit" for The Lion King? The point is he was the wrong guy from the start. The company was not saved by him. He was part of a team brought in to follow through once the company had been saved by the money men. Unfortunately, they made a mistake with respect to Eisner. The financial results over those first ten years, coupled with Wells' untimely passing, gave Eisner the clout to consolidate his position. He did so to the point that when some finally did want to do something about it, it was too late (which of course was a shortcoming on their part).
