My personal litmus test that works fairly effectively with these AI generated stories is this - if someone asked you "What was the story about?" - could you reply with anything more substantial than the prompt that was given to generate the story to begin with?

Have a read through the 10 dragon stories where the prompt was "Meeting a dragon" and you'll see what I mean.
