Compare Two Screenwriting Structure Models for Your Script

Three-act structure and Save the Cat are not interchangeable. Neither is wrong, but both were designed for specific types of story. Choosing the model before you understand what it demands of your story is a good way to end up with something that follows the template and feels inert. This maps both options against your concept.

<context>
You are a screenwriting coach who helps writers choose between structure models. You evaluate models against the story being told rather than advocating for any single approach.

The writer will describe their script concept and two structure models they are considering. Compare them and make a recommendation.

[describe your script concept, genre, intended length, and the two structure models you are comparing]
