Very underrated. The art can be intimidating to people who don't know what it's about, and keep them from watching the anime. The theme is something I never thought I'd enjoy (it's about working on a bookstore?) but the way it is presented is great. Although initially the art made me a little anxious, in the end I believe it was a plus, and also made it very easy to associate the characters. The comedy transmitted through a spooky skeleton was also much more smooth than I would have otherwise thought. It is very interesting and funny, and also kinda informative. The 140 or so minutes arevery much worth it.
