The aesthetic was really on point. And Villeneuve is really really good at giving a sense of scale on things.
Bautista, though with little screen time, was a very convincing Rabban and I am glad he is not wearing the Drax-stamp with him. He was amazing in Blade Runner, despite, again, his short time on screen. And pretty good as well in Knock at the Cabin.
The 1984 had good things, and I still believe their desert-suit was much better than the ones in DUNC. Their Sardaukars looks also more threatening in their heavy rubber suits.
