Thanks for the well thought out response. You probably are right. Iger almost certainly doesn't have the same growth opportunities as Eisner.
Conversely, most questioned the wisdom of the original Disneyland. Many questioned the wisdom of building a theme park on central Florida swampland. I vividly recall Wall Street criticizing Epcot, having close ties there. Disney-MGM Studios was questioned as being one theme park too many in central Florida, especially with Universal Studios being built concurrently. Yet there was considerably less pushback from Wall Street on DAK and DCA, Disney's biggest domestic disappointments. (The current Disney management team deserves credit for the DCA redo, their biggest success to date.)
The thing is, conventional wisdom often is wrong. Wall Street is dominated by number crunchers, and most number crunchers don't have a clear understanding of how to run a business. As a result, they tend to follow conventional wisdom. They are needed as voices of reason, but the person running the show needs more imagination and better instinct.
