For years, I have been talking about story structure (at least I have within my in-person writing groups). And for years, I've been trying to help writers understand that the antagonist is just as important to a story as the protagonist.
It all comes down to understanding both the role of the antagonist in a story and their nature. While I have written about this before, to quickly summarize, the antagonist is simply getting in the way of the protagonist achieving their goals, whatever those goals might be. But that doesn't make the antagonist a villain. In fact, the antagonist can be anything that is getting in the way, be that another character, the weather, societal norms, or the protagonist themselves.
When we're looking at story structure, there will be points within the story where the reader gets to see the antagonist in all their glory. Two critical beat points that are antagonistic beats are known as the pinch points.
Be advised that this blog post refers to beats and sections described in the Mohr Story Structure model.
