I'm a fan of the original, however I really enjoyed the new version. Villeneuve said it, go see it in the theater. I saw a review that said "Dune is too big for your TV". I would have to agree, it was visually amazing and does benefit from being on the big screen. Story is more clear, though some minor things were changed. Some of the changes, certain conversations and events occur at different times, and I felt this helped make the story a bit more clear. It takes a bit more time explaining things because there is more time to do so, but as a result it moves slower as well. I like where they ended it, is about where I expected it would stop. Casting was pretty good, no flubs like the original. Oddly, it sort of downplayed the Harkonin in this one. The crazy was a little toned down and they left out some of the depth of the side characters vs. the main ones, such as the Mentats.
The theater we saw it in has excellent sound, sound definitely does not disappoint with this one. I will have to watch it at home now and see if the bass comes along with it. WORM bass was amazing in the theater.
