Were there any fallacies in 'Citizen Kane'?

That would seem more a subject of a thesis. In any case, the biggest fallacy was that a powerfully intelligent and productive man would have the entirety of his life guided, shaped and controlled by the loss of one sleigh as a child.

I forget who said this, but the phrase "It was painfully Freudian." leaps to mind. People are a bit more complex than that, and the mass of men do not die mouthing the name of the toy they once loved.
