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.
Hilarious in Hindsight: At the beginning of the poem, when recounting the Ages of the World and saying how much his time period sucks, Ovid wishes that he were born either earlier (and been around when gods and heroes were) or later (as presumably things would have to start improving later on, right?) Now fast forward to the modern age... the standard of living is most definitely higher now than it was then.
Les Yay: Subverted. In Iphis and Ianthe's tale, the two girls are married as husband and wife, but Iphis has serious issues about how she'll be able to fulfill her role. Cue to magical Gender Bender. Amusingly enough, however, there's far more Les Yay fuel from Ianthe's part, who ignores Iphis' true gender.
The story of Erysichthon, a king who chops down a tree in the sacred grove of Ceres and is punished with never-ending hunger. He ends up selling all his possessions to buy food, down to selling his daughter into slavery (though she escapes through her Voluntary Shapeshifting). And in the end, he dies trying to eat himself.
What an Idiot: A lot of things could have been avoided if people stopped to think that insulting beings who are immortal and super-powered wasn't a very good idea.
Values Dissonance: A frightening number of the stories are about the divine punishments given to various rape victims for the crime of having been raped.
