I never actually finished watching Dune. I had two friends desparate for me to watch the movie/read the book because they were superfans and wanted me to join in.
But i got contrary and wouldn’t do it. I finally did see parts of it though and I could get some of why they really liked it – and I’m sure the books were way better etc — but I also never finished Lord of the Rings nor have I see all of Star Wars.
But that said, I must be in good company as I hear Frank Herbert was very good at what he did to have gotten an enthusiastic fan-base as he got. [and is probably WHY my friends really wanted me to read the book/see the film]
