Your Least Favorite Genre (for lack of a better word)

I was reading about a new movie by Barry Levinson, described as eco-horror and realized that sort of thing is my least favorite genre for a book or movie.Give me a horror story that is completely fictional like vampires, ghosts or zombies any day. Eco-horror is too likely to occur to derive any pleasure from reading about it or watching it. I have kept my distance from these sorts of books/movies since COMA, which seemed all too likely--and it is.

What subject matter do you shy away from?
