I’ll be seeing this soon but I want to first direct you to Michel’s review which, if you read any Dune 2 reviews, this one has to be one of them. 

“it is a special kind of evil how these movies profit off of a cultural non-specificity while vulture picking us apart, transfiguring our tangible realities—our style of dress, our food, our practices, our hospitality, respect, and reverence—into aesthetics to put on and discard once the press tour's over, in Stilgar doing sujood in his prayers and warning Paul to fear Djinn in the desert, in the Fremen hilariously speaking improperly pronounced Arabic in the most confident of tones, in an anti-colonial story getting twisted to a ghastly vacuous mass of mass appeal when we, as I've reiterated across many of my reviews in the past few months, are live witnessing MULTIPLE GENOCIDES of indigenous Arab and African populations.”
