I just watched this the other night for the first time since the 80's. It's so bad! 😆
And I say that as a lover of the book.
Oh god, the weirding modules!
"Muad'dib!" Pew! "Muad'dib!" Pew!
Lynch didn't want it to be a "kung fu movie", but the whole fucking book was kung fu! That's what made the Fremen better warriors.
They touched on the prophesy stuff, but never even hinted it was planted by the Bene Gesserit hundreds of years ago. The locals were chanting Muad'dib when he landed on the planet! He didn't pick the name himself.
So many unnecessary changes to the plot like Leto being confused on who was who and blowing the poison in the wrong face.
And I never get tired of being angry at the "monitors are projectors" special effect trope. You ever stare into a projector that's focused on your face? You can't see anything but a bright light. You ever look at someone who's looking at a monitor? You don't see the words on their face! "But it looks cool!" No it doesn't! It looks like shit because it's so antireality.
