Pain in the ass
I am surprised that Tarkovsky is not on the list. :shocked:
Tarantino belongs on there and in fact, I'd rank him higher than he is. Quentin speaks the same visual langauge as Scorsese, De Palma (The extreme end of the curve), Spielberg and Copolla. (Not saying his work has reached the level of these guys (although Pulp Fiction is close) but he is one of the very few filmmakers working today that is keeping the Auteur style alive in cinema.
He clearly understands films visual langauge.

The only reason I would disagree with you is that, in my eyes, QT really has only done ONE brilliant film: Pulp Fiction (And that was 15 years ago, which is worth mentioning). Jackie Brown, while I love it, is simply a very competent movie that showed he had room to grow as he gets older and matures. But nothing else he's done has really been that amazing.
I would actually lower Welles on the list for the same reason. He really only did one thing truly notable. The rest of his career was a disaster. To me a list like this should take consistency into account, a body of work. Spielberg, Cop, Marty, Hitch, etc all have had their ups and downs, but over all have produced great bodies of work.
