Famed Soviet rebel filmmaker Andrei Tarkovski once wrote:  "The dominant, all-powerful factor of the film image is rhythm, expressing the course of time within the frame."

What I get from it, and where I agree, is that it's really important not to think of storytelling time as a constant.

Some shots can express big changes and big ideas.  Other shots can express minute change. It's not that the big shots belong in some movies, and the little shots in others.  It's the contrast between the two that makes the movie what it is, and dictates the flow of time.

Not every shot in Iron Man is dressed to impress.  Some of them are about Robert Downey Jr. realizing something small, but useful.

Ignore the big shots, and you're making crappy student films. Ignore the little ones, and you're making Star Wars prequels.  Mind you, his point isn't about production value.  It's about the scope of the actions and emotions expressed.

Lost in Translation has both kinds, just as much as Iron Man does.

Of course, I'm not saying there's just these two kinds of shots...  It's a gradient, but you get the idea.
