Eisner had 2 distinct eras, the wonderful pre Wells death, pre EuroDisney era, and the horrible post Wells death, post EuroDisney era… unfortunately losing Wells and EuroDisneys initial failure turned Eisner from a parks loving dreamer into a budget focused micromanager.
I dont think you’ll get many arguments it was time for Eisner to go after he gave us DCA, MGM, and the Studio Park in Paris, it’s sad that he lost his love for the parks and went from beautiful ambitious projects like EuroDisney and AK to uninspired parks built around the cheap studio “theme”.
Unfortunately Iger has followed a similar path, early in his reign he gave us amazing projects like DCA 2.0, Pandora, etc and now we get cheap uninspired projects like Pixar Pier and Cosmic Rewind, an amazing ride stuck inside a huge blue box.
