I simply can't recommend this movie highly enough. The cast and scenery are, if nothing else, a tour de force unseen in modern cinema.
Unfortunately, even the dream cast could not help this film. Kyle MacLachlan's screen debut was quite promising, Sean Young and Sting also did pretty well. The casting was pretty good in general, but the movie just failed to deliver. Even as a director's cut.
I don't want to blame David Lynch, because I don't think it's really possible to fit the story of "Dune" into a 2-hour movie.
I don't want to blame the actors, because they were working with a bad script and a director who was attempting to make a 2-hour movie out of "Dune."
Nevertheless, the visuals are pretty astounding, and the costumes, sets, and special effects are all pretty great, especially the special effects when you keep the time in mind. Those shields look awesome.
And I can't really bring myself to HATE anything with Patrick Stewart and KMac.
Nevertheless, I love the book, but the movie fails at being a movie. It doesn't tell its story cinematically and the screenplay is all over the place. It is pretty cool to see the characters I know and love, and some of the parts of the book that I really loved are in there, which is great. However, others are skimmed over or simply left out. You can only really get the general idea of the story from the movie, and the parts of the story that you do see aren't even told very well. All in all, I'd watch it again. And I even enjoyed it for what it was. The book was simply much, much more.
