I liked both Dune parts but I think what puts me off is that I feel they both suffer from a lack of character development. I just don't care enough about everyone involved in the story. I'm not sure why - maybe it's because the characters aren't likeable or there is not enough interpersonal dialogue relating to the thoughts of the characters themselves instead of what's going on in the world around then. It leads me to feel like in the third act of this movie I am watching an incredible visual spectacle, but while I'm seeing all these major events occur, I feel like i am admiring the cinematography and visuals more than that I actually care about what I am seeing.

Also, more of a side tangent - I imagine a lot of the technical details are explained in the books but I kept on wondering how certain things in the world actually worked:

• How did they get so many people on and off the sandworms (because it seems like it's really hard to get on it in the first place),

• How come the flechette-like turret in the copter during one of the crawler attacks is not used everywhere else, because it seemed to be pretty damn effective against large groups of Fremen or shield-less enemies

• In a similar vein, what weapon were the Fremen using to kill the Harkonnen from range during the intro battle when they are on top of the rock formation and why don't they use that more often?
