I saw the movie first, then read the book after hearing it was different/maybe better, since aside from the bear, I found the movie fairly whelming. I ended up really enjoying the book, particularly the dream-like style. Authority, however, I found… really slow. I was intrigued by the premise, and the reveals were interesting, but the pacing was just glacial, imo, and it did away with what I’d liked about Annihilation. I did start Acceptance afterward, but was sort of over it at that point, and never finished it.
Link works for me, but here’s the original article. Movie is called The Day the Crown Cried.
