I agree with Villeneuve’s decision to make Chani the protagonist in part 2, because in the book Paul’s prolonged exposure to the unrefined spice further unlocks his mental capabilities, and IIRC both Jessica and Chani notice that he’s becoming increasingly aloof, and audiences need a grounded, relatable character.
I guess I’ll just crank up the colour saturation on my TV settings when the movie comes out on Blu-ray.
