I don't even know how to respond to the Kurosawa comment. You're obviously a smart guy, so I'll chalk it up to a temporary loss of perspective.
The difference between Scorsese and Spielberg is that
Scorsese has somehow retained his connection with actual people. One of the benefits of l Scorsese's iving in NYC, I suppose. All of Spielberg's people are based on a "theory of people" rather than actual knowledge of people. I won't go so far as to say he's a "hollywood elite" because I don't know what that means, but he should definitely get out and about more. Talk to someone other than his laura ahsley wearing hordes and studio executives.
