Finally nailed the essence of the book in adaptation worth watching. Is it a perfect adaptation? No. But a lot better than the previous 2 attempts. Only criticism is that if you don't have perfect hearing, Rebecca Ferguson's whispering is unintelligible. You'll have to rewatch with closed captioning. Whether it's the actress, director or sound editor's choice it was a mistake that spoiled parts of the movie. Anyone who didn't research and know that this was part one of two. Sour grapes, it was information freely available.
This is a difficult book to adapt. The first science fiction "complete" world, like The Lord of the Rings, fantasy world, with its own history, calendars (the year shown has nothing to do with our calendar), competing guilds, religions, touching on positive environmental change and stewardship becoming a multigenerational dream of a people, an eons past rebellion against a master race of artificial intelligences, leading to ban on any thinking machines and humans bred and trained as computers. Personal shield tech making projectile and energy weapons obsolete, bringing a return to the blade as a combat weapon. In the book, explained by excerpts from an encyclopedia in the future of the current story, at the beginning of each chapter, or excerpts from Benet Gesserit scripture. Hey, Jackson left Tom Bombadil out of LotR.
