I don’t want to take away anything harmless that people enjoy. You enjoy it and thats enough. Me personally it was by far the worst sci-fi novel I have ever read, and that includes that Heinlein novel the Name of the Beast. Which he deliberately designed to be awful as a teaching tool.
The only thing I enjoy about Dune is the jokes me and buddies have made about it over the years. A friend of mine is in IT and we would torment him with IT in the Dune universe basically being the guy who has to “service” the Mentant and clean the tank of the Navigator.
