is the main theme occurs mostly in Paul's own mind

and lots of explanations of the Bene Gesserit create-a-savior mythology

which are two difficult storytelling techniques to put on a screen

I thought Villenueve was smart to upgrade Chani and make her carry those thoughts with her as a character, instead of Paul constantly wrestling with himself and having vision after vision

the spacing guild, Thufir, Count Fenring are all great Dune subplots but are easily expendable

actually the spacing guild would have been cool, but that needed to have been built from Dune 1 -- explaining the importance of spice to the entire galaxy and why the Emperor himself would be so involved in Arrakis

hopeful part is, part three could be *way* better than Messiah, which I love as a conclusion for Paul but not the smoothest narrative
