First, Peter, I don't see anyone here who thinks that all change is bad.
It is true that some are reluctant to give any credit to Mr. Eisner, but at least they are willing to discuss the reasons why.
In the end, it's futile to argue about each other's lists of what attractions are good and bad. And arguing about the existence or lack of "magic" approaches total silliness.
To me, it's far more interesting to explore (1) what made
Disneyland and Walt Disney World something extraordinary, (2) how Disney took its eye off the ball, and (3) what recent improvements have we seen, and what else does Mr. Iger need to do to reach extraordinary heights again.
It seems like we lose you at item (2). Certainly there have been some good things created over the last 10 years (or whatever Eisnerian sub-period anyone wishes to examine); however, I'm thoroughly convinced that Eisner was taking many actions which over time were diminishing the greatness of the parks and resorts. Until the Ouimet regime, Disneyland was allowed to physically deteriorate, and its Tomorrowland essentially dismantled. Imagineering lost personnel, financing, scope of work, and influence. Feature animation, which feeds so much into the parks (including the actual Animation building at the Studios), was left to wither away. Merchandising became more aggressive, at the expense of the experience--see Main Street's shops before and after. Largely due to the extremely low unemployment in the Orlando area, hiring standards were lowered. At the same time, CM training was reduced. Elements of "good show" were lost, such as by opening Adventureland later, or closing Future World earlier. I'm sure A-V and YoHo could enhance this list.
So, in the minds of the Element, this is about more than the loss of Mickey Head Butter, or whether Mission:Space is enjoyable, or whether you can still have a great time at WDW (I know I still do). Heck, I've defended any number of changes, such as the closure of the CA Grill deck. It's about the larger issue of whether those folks at the Company who are now entrusted with the care and development of these places that we have an idiosyncratic affection for, "Get It."
It's not about whether Walt would have put Jack Sparrow figures into Pirates. Rather, it's about whether these things are being done with the same Philosophical goals as what (to our minds) made the Disney parks great in the first place--driven by story, excellence, and enhancing the guest experience.
