The new Dune is so artificially slow and full of itself. The old one with Picard and Mr. Mayor is so much more watchable for me and I genuinely love it. The new Blade Runner did the same thing, being slow for the sake of being slow does not make it deep or philosophical it just makes it boring
I felt the complete opposite. I've read all the Frank Herbert books multiple times and loved how in-depth they were. Dune part one was much better than part two because the first part spent so long setting up the universe and exploring different factions which I found really cool. Part two was like "well, all the hard work is done now so we can just have all of the action". No! The action is the worst part! I'd much rather 70% world building 30% plot.
As an aside, I also like how the technology was very rarely explained. Just the shields and the stillsuits I think. It makes it feel so much more natural and realistic because these characters live all their lives with weird floaty lamps and ornithopters and lazbeams, so why would they explain any of it to us?
