There is a difference between something being essential, and it being necessary. If you take your favorite book and strip it down to what is merely essential to tell the story, it would be butchery. The end result would horrify you. Essential is the bones of the story, but the soul lives somewhere else.
Patrick RothfussOne reason we love fiction is because stories have a comforting shape. They provide a resolution that's lacking in our regular lives.
