Fantasy is my #1; I will give almost anything a chance if it has strong fantasy elements. Post apocalyptic, superhero, alternate history, science fantasy, some supernatural, romance, and a few fandoms (especially Game of Thrones) are also likely to catch my eye.
As long as the plot's good I'm in. That says nothing useful though... so I'll say: sci-fi, fantasy, I'm curious enough about horror to add it, aaaand action? yeah, ok, sure, action!
