I read the book as teenager and enjoyed it. Many years later the David Lynch movie came out, and I thought he did well for the technology available then. I don't know if any movie can live up to the scope of the novel, but I'll check this one out when I can.
Read the original Frank Herbert trilogy when I was in High School and college. Then, about 20 years later, re-read them again and everything else that was written by his son.
Granted, everything after God Emperor isn't as good as the original 3, but hey, it was Dune and consequently, held my interest.
The original movie (and it's various extended cuts) did well, except for the ending, to live up to Herbert's original, but c'mon, nothing is going to capture that trilogy on the big screen. Sci-fi tried it with a mini-series and while it's a valiant effort, it feels too much like a Broadway production.
I'll watch this new remake, but based on that trailer, my expectations aren't terribly high...
