I know I'm weird because I absolutely despise Dune the book and the movies but I like everything else Frank Herbert wrote including Destination Void and its sequels, the BuSab stories, Eyes of Heisenberg, etc.
A lot of people do, but I think it is way too long and also overread. When I was a kid in the 1980s there were a lot of people who read Dune or Hitchhiker’s Guide to the Galaxy multiple times but didn’t seem to have ever read Heinlein or Asimov or Clarke or Dick or Pohl or E.E. Smith or anything in short-story form which were pretty important before the Tor books era.
