Honestly, do we really need another Dune? I love the novel series up to and including God Emperor.
I was fine with the miniseries a few years ago. I don't think this is really possible to do justice to as a movie. The basic story of Dune is not what makes it a great novel. When you remove all the politics and subtleties of the story, which you need to do in order to make a movie, you end up with what is at heart only a mediocre story.
