There is a scale on how much authors streamline their fiction. On one extreme end you can have a plot that is loose, where every scene doesn’t kill three birds with one stone (plot, character progression, show world building) and may only kill one. Messily. This results in plots that seem as if they can go any direction, and tend to be editors’ worst nightmares, because they are in danger of having no story, or if the plot does exist, it may never reach its destination. Done wrong, these feel like rough drafts and are generally mocked as such.
On the other end of the spectrum is streamlined fiction. Every scene is polished to shining, well-oiled, and heads directly towards the climax(es) and the book’s end. This generally ends up feeling like a Railroad of Destiny, where there is little choice but for characters to end up where they do. Even if the plot is original it still tends to feel predictable due to how much the author/editor trim the shrubbery along the way. Done wrong, these stories feel overworked until there is no spark left. However, elitist authors and editors tend to feel it is a mark of craft on how whittled down their plot is.
I have read fiction from both ends of the spectrum, but I tend to write (and long for) fiction that comes more in the middle. I want my characters to feel free, to end up on whatever path they may. I want my fiction to feel as loose and unpredictable as life, but to still feel like the characters are carving and shaping their own destiny from that unpredictability. I want them to grow, have epiphanies, make miracles happen, and change their world. To do so, they must walk a path, but it doesn’t have to be paved.
