Dumbledore and McGonagall's weaknesses are more apparent in Eliezer's fiction. Which would score realism points with me, except that the deconstruction of the perfect Dumbledore is balanced by the imagination of a perfect Harry.

Harry is far from perfect. He has his own glaring weaknesses. He's excessively clever (sometimes at the expense of wise or rational), his ego clouds his decisions, he is paranoid, incapable of relating to humans normally and shows disconcerting tendencies towards codependency.
