I had to watch Dune part 1 because if I didn't, I would not have known what to expect in Dune part 2. The movie was incredible. To see it on the big screen really makes a difference. You need to see every angle possible. I understand why it needed to be that way. I loved the movie. I would watch Dune 1 and 2 over again. I didn't like the scene where Feyd-Rautha died. But it was necessry if they planned on doing a third installment for Dune. The casting for this film was picked brilliantly. It fit them like they were part of the era of Dune itself.
