Honestly I don’t like the drab muted colour palette Villeneuve is going for.
I also don’t like the look of Baron Harkonnen as some sort of cyberpunk villain. I the book the Baron Harkonnen is described as having red hair and dressing in flamboyant, brightly coloured robes.
I’ve not read the books. I’m thinking about waiting until after I see the film as it will help prevent further expectations. That’s interesting though.
