I read the entire Dune series of books in the 1970's. Although good books, I can't imagine them making good movies. The story is overly convoluted and probably not very cinematic.
The previous attempt at a Dune movie was of questionable quality.
Frank Herbert tended to write very weird novels. His "Whipping Star" series of books are a good read, but weird as all get out.
The trailer gives us nothing to indicate that it will be any good. It could be another Battlefield Earth.
