Screenwriting: Drama into Story
The basic building block of screenwriting is the dramatic moment. Drama is the basis of a scene, but it is also the basis of each moment in the scene.
When there are two opposing forces with valid positions or equal weight - drama is created.
If the drama has significance, it will be of interest to the audience. To give significance to a dramatic moment, make sure the audience understands the valid motivations for both sides. To add depth to your writing, try to not think of drama as good verses evil, but as two opposing forces which cannot co-exist. This is a state of dissonance and the audience will crave consonance - thus you will hold your audience during these moments.
If the audience understands both intentions, the scenes will carry more weight and the scenes will feel of more consequence.
Often writers seem to feel that they need "connecting scenes" and "expositional scenes" between "key moments" to tell their "story." I would encourage every writer to think first of creating a series of compelling situations rather than a of string plot points leading the audience from "here to there."
If you can write about 45 compelling scenes which all relate to a unifying idea. You could arrange those to tell a solid story.
Story is the result of a series of dramatic moments, not the cause for them.
