Why the commercial engineering of formula storytelling is killing storytelling.
A formula is not how a story is built. A story can be checked against a formula of one kind or another, but that's where we get nonsense like the idea that there are only X number of stories that can be told, be it three, thirty-three or 108. There are indeed common elements to all successful stories, but they all come down to things that by themselves are not formulas: Do we care about what's going on? Do we want to follow these people to the bitter end? Do we think about what happened when it's all over and come back to it?
In the end, a real story springs free from any formula it could be compared to. And any story built directly from a formula, with no regard for its inner life or any respect for the harnessing of same, remains a formula.
