The Iger hate is quite something. I know this is a WDW forum and he hasn't been great for WDW, but Eisner was absolutely terrible toward the end. Some people seem to have bought into Eisner's self-delusions of being a modern day Walt who combined business acumen with creative brilliance. Eisner's judgement and ego became so shockingly bad toward the end that he seemed to be driving Disney off a cliff.
Eisner gave us DCA 1.0 and we would certainly not have the vastly improved DCA that exists today had Iger (or someone...) not taken over. I also don't think Iger has ok'd anything nearly as terrible as WDS. If anything, he seems to be plowing billions into finally fixing DLP. The brand in a general sense was beginning to tank when Iger took over, both in parks (jokes on The Simpsons about how bad DCA was, for example) and particularly in animation. Eisner's response to Dreamworks' success, for example, was to hastily shutter traditional animation and produce DW knock-offs like Chicken Little. When negotiations got tough with Pixar, he started slapping "Walt Disney" on low-grade computer animated films like The Wild. He was the guy who started Disney churning out an endless stream of lower quality DTV sequels like Bambi II.
Despite what some people seem to be suggesting, the company is now in far better shape than when Iger took over. Now the Disney name is at least associated with huge hits in animation like Frozen and Zootopia and some of the biggest franchises in live action film. I'm all for being critical of how Iger has managed the parks, and particularly WDW. However, I find it very hard to pretend that he is some sort of villain who has ruined Disney considering the company he inherited and where it is today despite my feelings about how WDW is being run. I honestly also think he's generally shown far more respect for the brand and its need to be associated with quality entertainment than his predecessor.
