What are some genre combinations you don't normally see in media that you'd think would be pretty cool? And not just like x-genre with y-genre elements but that the genres are primary in the story.
I, for one, would love to see a fantasy horror story. I think it would be a pretty fresh if the setting takes place in a different fantastical world as opposed to the modern world like most horror, plus the main thing that makes horror scary is the unknown, and you could really play with audience's heads not knowing everything about this whole other world making them question which parts are “normal” for the residents of that world and which parts are actually horrifying for them (and maybe it can even be both!)
Now go! Give me your genre OTPs xD
