This is great advice, it also works with dialogue within a scene. When I feel/sense a character's dialogue is unnecessarily wordy, I'll ask, "What's their point?" It seems counterintuitive, but cutting dialogue down to fewer words can make dialogue more powerful and emotional. And recoup page "real estate" throughout your script.

Traci, agreed. While we want to be entertaining in what we write, we also have to be super mindful of advancing the narrative. And asking that question -- What's the point of this scene, what's the point of this side -- is a great way to stay on target.
