What's a genre you just can't get into, no matter how hard you try?

Everyone's got that one genre that they just can't click with, no matter what. Whether it's the stories, the authors or the culture surrounding the genre, you just have no interest whatsoever. What's yours? I'm happy to go first - I can't stand Historical Fiction. The idea of taking real historical characters to tell your fictional stories about feels like bad fan fiction. What book in your favorite Genre made you cringe while reading?
I remember reading a book called "The Wandering Engineer", basically a cyborg engineer gets frozen in an escape pod and woken up in the future on a damaged ship crewed only by women and they all fall for him as he repairs their ship with his amazing feats of engineering. Also they all wear fetish costumes like "sexy nurse" for some reason.
I love trashy sci-fi, but I felt like I almost dislocated my shoulder from all the cringing.
