Top 10 + 1 reasons story openings can fail:

1. Not enough happens.
2. The story’s genre is not clear.
3. It’s not clear what the story is about.

4. It’s not clear who the protagonist is.
5. There’s nothing unique about the story to set it apart.
6. The story is not grounded in setting.
7. The protagonist is not likable or admirable and readers can’t relate to him/her.
8. The story does not engage the reader’s emotions.
