The problem with Dune was that it sucked. The picture looked awful, everything's so dark. The special effects were atrocious. The shields in particular looked so terrible. Even at the time it was criticized for its bad SFX, especially when movies like Star Wars RotJ which had come out a year before looked so much better. Many of the cast members were woefully miscast. Kyle MacLachlan was too old to play Paul. And Freddie Jones as Thufir Hawat? He looked more like some mad scientist with those ridiculous eyebrows and hair. The whole thing looked like some bad B-movie production. I heard Lynch has disavowed the movie and refuses to talk about it. I don't blame him. This movie actually made me avoid reading the book for many many years because of how bad it was and how terribly confusing it portrayed the story and plot and how weird everything looked.
