When it comes to setting, why might the author of a utopian novel choose a mountaintop or the bottom of the ocean? Why might this be a difficult setting in which to place a dystopian society and where would it be better?

The reader will get a sense of wonder or fantasy from these kinds of locations.

Explanation:

Your average reader probably doesn't live at the bottom of the ocean, so this kind of setting can feel almost fantastical, which can be good for a utopian story, but not so great for dystopia. Many authors of dystopian stories want their readers to get a sense of "this is how my society could be" or to draw clear connections with the world they already experience.

It's easier for the average reader to make connections to their own life when the dystopian story takes place in a city or other setting that they have, in some way, experienced.
