I haven't read the book either, but I saw the 1984 version when it was out in theaters, I didn't like it very much back then. Something about sandworms and spices, I found it very muddled and confusing. I started rewatching it yesterday just to jog my memory and realized the cast was great though - Sting, Patrick Stewart, Brad Dourif, and even Das Boot's Jürgen Prochnow! Still, it's three hours worth of confusion, not sure it's worth the while.Dune (2021) - never read the book or watched any of the previous adaptations, but seems pretty good. I like sci-fi though. But I'm not a nerd. This seems like a movie better to watch in theater than at home like I'm doing.
The 2021 version is all right, it's probably not something I'll remember years from now. But I was entertained, and I will remember that I was just as confused, and that's because I didn't have access to subtitles and consequently misunderstood half the dialogue. The whole spice thing again... I thought they were fighting over a spice like curry or nutmeg or whatever. I was thinking how did they convert something like nutmeg into a fuel that would make a spaceship run? I don't understand!
Anyway, whichever version of Dune I think (for me at least) it is one of those movies where having a little background info is helpful because the movies don't necessarily make everything clear.
