And sometimes the feedback comes in the form of constructive criticism, and that's good too. It's especially handy when it comes from others in the writing field. It's how we improve, how we grow.
But every now and then I get one of these:
"Good story, but I saw that ending coming."
I enjoy a good twist as much as the next guy, but really? For me, the story is about the journey, all the things that happen to bring you to the end. And sometimes that tale brings you to a logical conclusion. It might be predictable, but it's what's supposed to happen. The joy in reading is in the story itself.
Sometimes there is a twist at the end, and that's always fun. Personally, I enjoy these stories more when there are little winks and nods along the way. Foreshadowing is a lovely tool, and a clever reader will be able to guess the ending through the clues the writer drops. It's like being let in on a private joke.
A twist at the end of a story just for the purposes of yanking the rug out from under the reader rarely works. These endings often feel contrived, and the reader feels cheated. The deus ex machina is a rarely appreciated device.
A good ending should be organic, tie up loose ends, and resolve the central conflict. It needs to be true to the story in order to be satisfying, and that there should be the author's goal.
So maybe you didn't get the surprise ending you expected, or maybe you picked up on the clues and guessed the outcome. If you didn't enjoy the story, or felt that the ending was a let down, by all means make it known. But a story without a twist is still a story. Enjoy the ride.
