Why was Dune so successful despite being largely inaccessible to a mainstream audience? How did Herbert manage to write the best-selling sci-fi novel of all time (surpassing classics such as the works of Asimov and Wells)? While rumors of its reboot arise, why might a major studio (Legendary Entertainment) take on such a sprawling project?
Overall, what is the appeal of Dune, and why has it been so enduring?
