I’ve read several of the books. I saw the David Lynch movie. I know the story of Dune pretty well.
This was, in my opinion, a very confused trailer. I can’t imagine too many average people seeing this and thinking, “That looks interesting”. Now, I’m not saying I didn’t recognize most of what was going on, but I think most people would just say WTF?
I agree—the trailer does not bode well for this movie.
There are so many outstanding SF stories that have not been made into film (that audiences would love!)—it just pains me to see them try this again...
