As awesome as this movie might have been, I'm content with _Dune_ remaining a book -- a beautiful, mind-blowing book. Thank god there weren't any other attempts to adapt it for screen.
What I would like to see, however, would be small focused shorts; that could go over well I think (sort of how Neill Blomkamp and Jackson did those Halo shorts).
Maybe it doesn't match up to the book, but if I ever read the book it would only be because of the miniseries and comments that the book is even better.
