Which aspect does not typically characterize a three-act structure?

In a traditional three-act structure, the primary focus is on the narrative progression and the development of the plot through distinct segments: the setup, the confrontation, and the resolution. The setup introduces the characters and establishes the context and central conflict. The confrontation presents the main challenge or antagonist that the protagonist must overcome, showcasing rising tensions and pivotal turning points. Lastly, the resolution brings closure to the story, resolving conflicts and tying up loose ends.

While character transformation can certainly be a significant component of many stories, it is not a defining feature of the three-act structure itself. The structure primarily emphasizes the progression of events and the resolution of plot conflicts rather than character development. While character changes often occur within these acts, they are not a structural element that defines the three-act form. Thus, character transformation stands out as the aspect that is not a core characteristic of the three-act structure.
