I get frustrated with books that should have been novellas and maybe even started that way, but for whatever reason - giving people their money’s worth or something else - become full length novels and suffer for it. I love chunky novels, but if it’s a novella’s worth of plot and everything else is junk filler, not even a quirky side arc, it makes it a less impactful experience. One thing I really appreciate about digital publishing, despite my love of physical books, is that it makes novellas easier to produce & cheaper to sell profitably in that format, which means more interesting stories are being told because there are fewer restrictions on format & length. Not every story needs to be a full novel. It’s the same thing that’s happening in TV. Love, Death, and Robots isn’t A+ TV but it’s embraced the streaming format and has done away with standard episode lengths. Obviously there are other examples but that one has the most length variety in popular TV that I can think of currently.
