Eh, isn't that kind of what makes him great though? He's extremely talented, intelligent, focused, and driven. He's had people trying to exert control over his projects his whole career, and he's proven himself to basically always be right over and over again. He knows what he wants and always delivers, on a scale literally nobody else can. It's his vision, and he wants to make sure it makes it to the sceen that way. At least that's how I see it.
