Mr. Captain, your history of Hollywood is rather interesting. For all of Walts failures, his studio was one of the few studios from the Golden Age to remain independent. Remember MGM went bankrupt and has been sold dozens of times. 20th Century Fox bankrupt as well. Paramount went to Gulf+Western long before anyone heard about Viacom. Universal was eaten by Music Corp. United Artists went to Transamerica. Republic, RKO, and many others simply vanished. Funny how Walt was able to steer his company through when all of his contemporaries hit icebergs a long time ago.
What gave Disney its independence was
Disneyland (which the business people were against), the move to television (which the business people were against), and continuing to produce animated films (which the business people were against). Perhaps if Walt had stayed making Laugh-O-Grams, the business people would have been happy, but things might have worked out differently.
To say that Walt set the current path is akin to claiming that General Electric is doomed because Thomas Edison never thought of the jet engine. At what point did Walt decide on buying a fourth-place network, spending the gross national product of Peru on the internet, building theme parks no one will pay to see, and giving the CEO three quarters of billion dollars? I just cant find that chapter in the Bob Thomas book anywhere! It is up to the current management to solve the problems that they created, not shift the blame on those long dead.
If the only defense of the people now in charge is to simply trash everything that came before them, then Disney truly is finished as a company.
