The "Twist Factor" refers to the element of surprise or unexpected developments in a narrative, often used in storytelling, films, and literature. It enhances engagement by keeping the audience guessing and adds depth to the plot. A strong twist can change the direction of the story, revealing hidden motives or altering character relationships. In the context of screenwriting or novel writing, the Twist Factor is crucial for maintaining interest. Writers often employ techniques such as foreshadowing or misdirection to build up to a twist, ensuring that it feels both surprising and inevitable when it occurs.
