I read through everything actually written by Frank Herbert. I tried one book written by his son (Brian? I forget) and oh my god it was unreadable so that was the end of that.
The Dune prequels are so godawful I only read 4 of them before giving up in total disgust. (What, I was trying to be a completist.)
We just rewatched the extended-edition "Alan Smithee" original last night and while Denis Villenueve's version may end up being, objectively, a better movie, it will never ever replace this classic hot mess of a movie in my heart. SO MUCH loud whisper-thinking! TWO HOURS spent on exposition only to rush through the last 400 pages of the book using voice-over montage! SO MANY reused shots in battle scenes that actually just could have been made shorter!
And of course the sheer joy of Patrick Stewart fighting Kyle MacLachlan inside these very convincing 1984 digital effects.
