dune is about the violent extraction of resources from the ground (and human) by imperial force warring for control of the planet. it tells the story we have a difficult time understanding due to the fact we're living in it, the story of colonization that keeps insanely plundering in the inevitable collapse. 

it's one of the few science fictions i've read, many years ago. it's the story of the colonized earth. i was dumbfounded, enthralled. i'm still dumbfounded and enthralled. 

they will try to make a film about it and it will never be as real as the book in your head, but with the book in your head you may have a greater appreciation of the sincerity and reverence of the film, if it has those. but what are we to make of reality.
