But seriously. I think a man with the vision of Walt would've understood that one can not govern 45 years over one's grave. I think Walt - if we were to dig him up from underneath the Castle and defrost him - would walk around WDW for a while, a bit bewildered, then withold judgement until he had had the opportunity to catch up with modern culture, movies, busines practices, tastes.
There is a lot Walt wouldn't like about modern WDW - from the point of view of himself in 1966. For one, Walt would disaprove of all those coloreds working in the parks.
Or would he? Maybe he would move with the times like everybody else. What Walt would've thought knowing what they knew in 1970, never mind what we know today, is almost complete speculation.
