Saw the movie last night. Loved it. I am a prior book reader and have read all of the original Frank Herbert Dune books. Reread Dune itself a couple of years ago in advance of DV's Part One. Will likely reread Messiah before the 3rd seemingly inevitably comes out.
Lot of my thoughts have already been hit on in one way or another. This movie had a handful of truly epic theater moments that resulted in just a freaking great movie experience. Chalamet killed it in this movie. The speech scene was nails.
High points for me, outside of that speech scene, off the top of my head: opening action sequence, the reverend mother pass down, the worm call/ride for Paul, Paul and Chani attacking the spice harvester, obviously the final showdown knife fight. I could probably add more high water marks and that is a testament to how great of a movie this is.
Unexpected takeaways: I thought Pugh did an excellent job and I was really impressed by her. Stilgar was also a great character, Javier did great in that role and bringing a lot of unique charisma to the screen and story, and I knew it was going to be a movie with a lot of great action and fighting, but the Fremen and dessert scenes with the story building there were done really well in my opinion.
All in all, thank you DV! That movie was a great service to the wonderful source material.
