What ever happened to predictability? The milkman, the paperboy, evening tv?

(Okay, I may be dating myself there with that reference but I couldn’t help myself.)

I recently finished up an outline for my next story. It’s about a girl whose chance reading with a psychic leads her to discover her true destiny is as the one person who was meant to banish the Jersey Devil forever. The momentary elation of finishing a solid outline was quickly eclipsed by my old friend, self-doubt. Self-doubt whispers to me that it is sure there are dozens of Young Adult Jersey Devils books and they are all way better than anything I could have possibly dreamed up. Self-doubt also told me that my characters were flat and the whole story was impossibly predictable. *sigh* Despite anything self-doubt tells me, I’m going to plow ahead with a first draft.

Can a story be predictable and still good? Are there any great, predictable stories?
