Given how good the book was i really was not expecting too much from this "mini series" or 4 hour telemovie. It really was a lot better than i had expected, lacking was the C grade costumes and special effects I was dreading. Overall the story is told quite well however there are some deviations from the books and many things/facts/events are either glossed over or ignored. However for fans of Dune its well worth the time to watch.
Would i pay $30-? Maybe, but i hired it and watched it so no need to buy. Probably could watch it twice, but that's about it. 3/5 but 4/5 if you love Dune.
