Plastic, I wouldn't do that. Can't you try to rent it first, or check the website and see if they plan to air it again soon.
I did NOT like the Sci Fi Channel one, and I do not think it followed the book very well, though my memory of the book isn't that good. The actor who played Paul didn't do it for me (not many would after Kyle M.), but I'm a confirmed fan of the movie. I read the book after seeing the movie, and I loved it. I do recommend the original book DUNE. However, I never read the sequels, though I would be interested.
I could be wrong about the accuracy of the sci fi version, but I still found it lacking in entertainment value.
And yes, the Lynch movie does leave out elements from the book, but it's just such a wildly interesting movie. I think it was way ahead of its time in art direction/set design for science fiction. Shoot, before that we had Star Wars where everything was grey plastic, and then the Star Trek series, more of the same grey plastic. In Dune, the sets are made with real wood, real stone, real metal (or made to look like the characters lived in a world where those elements were still utilized), and I think that's realistic. Just b/c plastic is great doesn't mean we want to live with plastic everywhere in the future.
I really love that movie. It was almost the first DVD I bought after getting my DVD player and I've got 2 diskettes of the soundtrack - which is fantastic. [Edited on 25/1/2002 by Yummy]
