I fully agree with this idea. I would argue that a film has always been a collaborative effort and that the idea the director themselves is the sole arbiter of its greatness has been a myth. I would be willing to give more credit to the hyphenate mainly writer-director, many of the directors in the former category are, with the possible exception of John Ford. Billy Wilder has been my favorite director of all time, but he doesn't have the same visual style from film to film. That said, I'm pretty sure his dialogue more than carries it. Similarly William Wyler, who was the most nominated director in Oscar history, made so many great films but it's pretty clear that he falls in the latter category.. Scorsese and De Palma have their own visual styles of course, but much of Scorsese's best work is in large part because of his actors and of course his editors such as Schoolmaker (?) and De Palma has a similar level of it based on editing and music as much as anything.
