Raymond, thanks for your comments. Every writer is different. Every story is different. Some stories require more dialogue than others, so that’s a consideration. Some writers are stronger with dialogue than action, so that’s another consideration. There’s no right or wrong, we do what the story requires and where our strengths lie.
That said — and coming from a specific perspective of dealing with students who default to using dialogue to move the plot forward — it is ALWAYS a good reminder that movies are primarily a visual medium. That means scene description. We may look at scene description as the dialogue of action, if that is at all helpful for a writer to bring the same care and attention to those words as to the words we write for character dialogue.
Whatever we do, the story ought to be the ultimate arbiter. What does IT need to be told in the best, most entertaining and effective way?
