Spoilers make stories better!

A researcher asked people (aka college undergraduate psychology students) to read some short stories, but some of the students had a spoiler paragraph at the beginning that revealed the twist in the story.

Surprisingly, people rated the spoiled stories as more enjoyable. When you know there's a secret, you can read the story and see the hints coming. I think we still enjoy being surprised sometimes, but we are more able to see the quality of writing when we know more of the details. Having a story "spoiled" makes the first time reading it like reading it a second time.
