I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Except for the movies and TV shows, which I didn't privately grade this year, these are things that got 1.5 stars or less (although not all of them - again, based on "gut feelings"). I hate that it's so much easier to explain why I disliked something than why I liked it.
