Non-fiction: the story must be interesting, informative, and well told with facts which enhance my understanding of life or provide spiritual enhancement.
Fiction: a good story should make me think or provide pleasure--preferably both.
I have no interest in an author's "experiment with words". I am not into "shock factor" nor exploring the depravities of the human soul. I do not need extreme emotional conflict or senseless drivel. I have very little interest in characters who demonstrate no common sense.
