I haven't read the book for years, but have read it several times. There are parts of the book that I skip when I reread it. I saw the second half of this part 1 and liked it but did think it was moving slowly--much like the book. My partner loved it, one kid did like it while the other one got bored early on. The kids are both 9.5. I told my partner some of back story afterwards like why the emperor has it in for the Atreides.

IIRC, in the private quarters--blankets, rugs--in the sietch, and in the women's clothes, they do use bright colors.

Have you seen and liked Lawrence of Arabia? Because it's definitely in a similar style and story.
