I also watched Dune.... and found it to be boring, and forgettable.
Villeneuve is a very stylist director with great visual style, the settings of the shots and presence of space in scenes are excellent. But his characters and how they are portrayed are lifeless with no emotions. It's hard to connect with them when there is no sense of tension, urgency, loss etc or even care for them on this journey. All monotone. Surprisingly Momoa is the saving grace as he seems alive compared to the rest of them. When Paul meets Chani, the girl he dreams about, it's so meh, the build up is totally lost. As well as the the Harkonnen's, boring dull villians. They are suppose to be exciting, strange, interesting, and you want to see them lose, but you don't here. I found this to be the same in his other works, Bladerunner 2048, and Arrival, great visual style but souless characters.
I find Dune to be a very controversial topic. I believe the source material has great original concepts but is generally flawed how it is written, and is difficult to translate into a movie no matter what. This new version does some things better, but leaves out plot devices and didn't really set the stage properly, like motivation, the emperor and what is going on between the 2 houses.
I think the 1984 version is still better, more charismatic cast, even with the cheesiness and Pickard running around with a pug, at least it was creative and exciting then bland with nice visuals.
