The others were actual answers so they’re cool. But your response is almost a non-sequitur.
Have you structured all the media you consume so that all themes stay consistent to a single genre? Ok, all the vampires go in horror, but do the werewolves go in horror too?
You’ll have to fight fantasy hard for that one.
What? Yes, they go in horror fantasy, as neither of them exist in reality. The point is Interview with a Vampire explores disturbing themes. Because it’s a horror story.
Ah, horror fantasy! You’re saying that we can mix and combine genres!
Hmm, are there rules to these combinations? Or can you just mix any of them together both willy and nilly?
Could you combine, say, vampires from the “horror” camp and ill-fated relationships from team “romance” like some literal, literary Romeo & Juliet? Would that not be a “Twilight”? Or would that be more “romance” than “horror”?
