I've seen the rare movie that actually is much better than the book. The film version of the Shipping News, for example, is much better than the novel. And, while it isn't a movie, the televised version of Westworld is a great deal better than the sketchy screenplay that masquerades as a novel. Same for The Handmaid's Tale, which is more of an interview of a subject in the past. The television version is more compelling, although the movie was also good.
