If someone prefers Dune 1984 to Dune 2021, I can understand it. It's weirder, more fun, has cult status, maybe they like the worms better.
If they prefer it because it's "closer to the book" I am allowed a *very strong suspicion* that it's because Liet is a man. Other than that and a few minor things added from prequel books, 2021 stays much closer to the book.
@clacke I rewatched the 2021 Dune at the weekend. It's even better than I remembered.
It's been a long time since I saw the 1984 version, but I remember being very annoyed by the fact that that film largely missed the point of the book.
