I have a few:
- Chosen ones, fate, destiny, &c. When you get down to it, a story with these themes is one where a single person or handful of people is ontologically, cosmically better and more important than everyone else. It's eerily similar to that right-wing meme about how "most people are just NPCs" (though I disliked the trope before that meme ever took off).
- Way too much importance being given to bloodlines by the narrative (note, this is different from them being given importance by characters or societies in the story).
- All of the good characters are handsome and beautiful, while all of the evil characters are ugly and disfigured (with the possible exception of a femme fatale or two).
- Races that are inherently, unchangeably evil down to the last individual regardless of upbringing, society, or material circumstances.
I think it also has something to do with the bourgeoisie wanting an escape from bourgeois problems. This is one reason why stories like Game of Thrones or even Dune (space feudalism) are so popular. Capitalist class struggle infuriates the bourgeoisie, since they are so obviously the bad guys, which means that they prefer to escape to simpler times, when the bourgeoisie was the underdog, and the evil, petty, but entertaining feudal ruling class was running things.
