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.
Values Dissonance: The depiction of the slave in most versions is... not exactly something that would go down well in the modern day. She's always portrayed as evil, usually as an idiot, many versions mention her mistress beating her as if it were no big deal, and most of the older versions spend a disturbing amount of time describing how disappointed everyone is by the mere fact she has black skin.
The Woobie: The first two maidens. Ironically, Basile's variant implies that they are restored in the end.
