What is the basic premise of the Dramatica Theory?
That 1) the vast majority of fictional stories attempt to make an argument about the right or wrong ways to solve a problem; 2) the story embodies the author's perspective on that problem; and 3) the characters, plots, themes and genre form a model of a single mind trying to work its way through the problem.
Dramatica not only defines patterns in stories, but relationships between those patterns. By understanding those patterns, users of the Dramatica theory and software can find logic holes in their plot, characters, and themes.
