I've also been watching a channel called NERD COOKIES. She has some pretty comprehensive videos that focus on one subject throughout the lore.
Anything beyond Paul recognizing her from his dreams, her being the daughter of Liet-Kynes, and her having Paul's children is an expansion of the character. Some things that were a product of the time it was written I am happy to see fiddled with. It makes sense for the neo-feudal society that's arisen in the Known Universe in the millennia since the Machine Crusade, but the Fremen sure as heck aren't part of that. They should be much more egalitarian and meritocratic.
It's a thing I've scratched my head over since she and Awkwafina became a thing over the last decade. They're good, they've won accolades, but their success has been very niche until recently. Not the sort of mainstream megastardom I tend to associate with other single-name personalities like Shakira, Beyonce, Cher, Prince, Sade, Elvis, Enya, etc.
That, and next to Jason Momoa and maybe Dave Bautista, she probably has the biggest name recognition of the entire cast.
Her role is much more prominent in Dune Messiah. In the original novel she's basically Paul's anchor to his humanity and emotions. I'm not saying they can't expand or come up with something that's interesting but I don't think she is that much of a focus of the story.
I have often wondered that too, his music is really bland to the point of being instantly forgettable. It's funny how, what I would consider great contemporary composers like Ramin Djawdi or Klaus Badelt, came from the Zimmer music factory but have composed great scores like Iron Man, Game of Thrones and The Time Machine.
one of 'the best' - I give points for the lines from the Lynch version, A+ for creativity
