This was fun! Usually I'm looking for a story that contains a few of these elements, of course, and even in my favorite tropes/genres there are plenty of stories that make me hit the backbutton with inhuman speed (I'm looking at you, genderswap fic!). I tend to find myself going back to warmer, more comforting stories than to the bleak angsty ones if I am doing a re-read, but for a first read I'll usually try anything if it's well-written and it's a fandom I'm familiar with.
