Just got home from Dune 2, and while my thoughts are still moving around about it, one interesting thing that struck me is how eerily well the three screen adaptations of that book map to the three times I've read it.
My first reading as an early teen tbh I was not equipped to really follow the intricacies of the story, and what I mostly got out of it was a disjointed mishmash of intense weird imagery and incident—compelling even if not at all coherent.
My second reading was in my late teens, and that time I was able to follow and understand the beat for beat plot even if some of the deeper themes flew over my head, which is very much what the faithful-to-a-fault hyper very literalistic Sci-Fi miniseries adaptation.
On my third reading a few years ago in my mid thirties, the tragedy (both in the vernacular sense and the classical one) of it all really hit home in a way it hadn't fully those previous readings—the curse of prophecy, Paul's hubris at believing his knowledge of the path ahead would allow him to steer away from tragedy when in fact his every move led inexorably towards that bloody future and the modern sense with stuff like the co-option of the fremen's righteous cause by generations of the BG's manipulations. I was a little taken aback that my younger self read this book as some grand tale of heroic adventure. And without getting too in to specifics, hoo boy does Villelnueve steer hard in to those aspects (mayyyybe to the point of making the subtext a little too much text, still stewing that over), especially in part two.
