Very tough question because it can be layered with lies while at the same time exposing life-truths, it really depends on who the author is. I think good fiction to be an ultimate exposer of life-truth personally. I think that because if a story, movie, or book is so outrageous in its content then it will not engage the audience. The Star Wars series is a good example of that. Everyone took the movie series as a fiction, and rightfully so; when you view the movie within context it seems feasible that a lot of the movie can be true. The famous opening line "A long, long time ago in a galaxy far, far away" seems outrageous, but when you view the vastness of the universe it's almost equally outrageous to think there wasn't civilized life forms that tapped into higher sciences that humans have so far not uncovered. The concept of the "force" in Star Wars is very similar to a lot of Eastern teachings of "Chi" and "life force." So although the movie is a fiction and very far fetched through the spectrum of the average human's experience, it still has an element of potential life-truth inside of it.
