Curious to hear how you and everybody feels about it, the reviews seem to be all over the place.
Turns out the Sardaukar are something white supremacists/Neo Nazis might admire, quite Nordic, and not what I expected from reading the books, which was for them to be something more like The Immortals of the Persian Empire, and the officer class of Napoleon's Old Guard. I sort of liked that the film heavily delved into what the books barely mentioned, IIRC, that the Sardaukar had a pseudo-religion that suited their warrior mystique. Though the film took that to an implausible extreme, unless you disregard the book as Canon. I also caught a whiff of censure of some who call themself Christians, with how the human sacrifices were staked out. I suppose that scene was also suggestive of how the Sardaukar, once they proved themself, saw themself as being elevated far above normal men, and I have to approve of getting that into the film.
And yet again one of the most deadly killers around, a Mentat assassin who was so dangerous looking (and with totally blue in blue eyes courtesy of massive consumption of his Baron's spice stores) that he could blend in with the natives on Arrakis, namely Piter de Vries, isn't really done justice. Brad Dourif still holds the distinction of providing the most interesting rendition of that character, even if given some bizarre lines to speak, and acting a bit like a tweaker.
But the high quality of this production of Dune should please most who watch it.
I dread to anticipate how part two will portray Count Fenrig. Lol, imo he should be shown as being like if Val Kilmer's Doc Holiday used edged weapons instead of pistols, and lived to be a hundred while honing his skills, including the ones related to slyly breaking people's balls.
The way Val Kilmer's Doc spoke to Johnny Ringo being quite similar to how Fenrig broke the Baron Harkonnen's chops when visiting Geidi Prime. lol
Apologies for the rant, I needed to "vent my spleen" and expel the "bad humours".
