Whether they are exploring the stars, escaping dystopias, or making the world a better place, these women are what science fiction is is all about. Anderson. A prequel to the original Dune, it tells how the Sisterhood of Rossak evolved into the Bene Gesserit.
All three books interweave the development of the Sisterhood, the Mentats, the Navigators, and the Suk Doctors. This spinoff is more like Game of Thrones than it is like Dune. Having said that, Dune: Prophecy is everything I hoped it would be and more.
I have to start by saying I've never read the source material or seen the original movie. My experience of Dune is predicated on the two Dune movies that have come out in the last few years starring Timothy Chalamet and Zendaya. Those two movies (especially Dune: Part Two) are two of my favorite movies I've seen over the last few years.
Dune: Prophecy is a series that takes place 10,000 years before the Dune movies and is about how the Harkonnen sisters started the Bene Gesserit as they fight off forces that threaten the future of mankind. The most important thing about this show is it does exactly what it sets out to do in the fact that it deepens our understanding of the Bene Gesserit. You don't have to have watched the two Dune movies to enjoy this but you'll definitely enjoy it more if you have.
