Sarah: Ow! It bit me! 
 Hoggle: What'd you expect fairies to do? 
 Sarah: I thought they did nice things, like... like granting wishes. 
 Hoggle: Shows what *you* know, don't it? 
 --Labyrinth (1986) 
 The Night Fairy is not a typical fairy story with princesses and wishes. Flory is a night fairy who, after being "attacked" by a bat, chooses to live as a day fairy. The story is a bit rambly in exploring the world and meeting new characters, which I expect is fine for a child audience, but was not all that interesting for me. 
 What I don't like is that the story contains many bad lessons, such as: 
 * Becoming disabled is reason enough to abandon your identity. 
 * You can rearrange your whole schedule to avoid those that you irrationally fear. 
 * It's okay to use people if they are using you back. 
 * With great power comes the ability to threaten, bully, and enslave. 
 Though not all of the characters put up with Flory's crap, none really put her in her place, and I'm not left with the impression that she has learned anything or developed into a positive role model. Maybe she's not meant to be.
