Not if every director who tries, refuses to stick to the story. Even the David Lynch version made changes because there were technical limitations to what he could show onscreen. But, that isn't the case anymore.

There's no real excuse for making these kinds of changes, except thinking that your story is better than the original. And if that's the case, then write your own story, and don't call it "Dune".

As far as I'm concerned, this is just another form of plagiarism. He's using the Dune name recognition to sell tickets to a completely different movie.
