As much as I loved the David Lynch movie, I am afraid they will not come close to the experience the book gives when reading. It's the same as with Ender's game, if you really want to take the awesomeness from the books to the screen, you have to make a non-Hollywood movie. And that is not happening since the audience doesn't have the patience anymore to sit through dialogues and voice-overs that portray thoughts. It would become too boring for most.
This might just become another Sci-fi action movie deprived of the depths of the book. But... let's wait and see.
