Erm, Lin's not actually just an action director, you know? After Tokyo Drift, I honestly didn't think I'd ever feel the need to defend him, but he is exceptionally good at his job when on form. Modern Warfare, Interpretive Dance and Introduction To Statistics are three of the finest things I have ever seen. Sure, one of those is based on action conventions, but still. The other two most definately are not. I agree with Silverwook, bit off beat, but interesting, and I think he could do alright.
And since when was the director so important? I remember a time when all that mattered was that Kirk was in it with his crew. And then Picard with his crew. And they were doing cool things. IN SPACE! (Athough in reality, Picard and his crew never really showed up. Just some angry old man with some familiar looking guys that did stuff for him).
