These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Designated Villain: Janie's first husband, Killicks, if you think about it. We're supposed to read him as cruelly trying to make Janie into a "mule," but when you get down to it he only wanted her to do as much work as he did.
Esoteric Happy Ending: So the great love of Janie's life is dead, she is socially stigmatized by her community, she had surrendered just about everything she had to be with her love, and now she returns to the place she had started from.
Fail O'Suckyname/ Unfortunate Names: Who Flung, Bootyny, Sop De Bottom, Lil Bit, Double Ugly, Stew Beef. These are actually characters' names. I'm not sure whether they're their real names, but if they are, their parents should lose their parenting licenses.
Values Dissonance: Tea Cake beats Janie to "show possession" of her when he's jealous; this is presented in romantic terms. Complicated by the fact that she sometimes hits him for similar reasons. In both cases it's shown as romantic, as well as emphasising that they're equals.
Vindicated by History: Hurston died in obscurity, and for a period of time, all of her works were out-of-print.
