I bought this DVD recently, after a 20-year lapse since I last read the Dune books. With only a vague memory of what was supposed to be going on, the movie was pretty much incomprehensible.What was the reason for Leto II transforming himself into a sandworm? I don't remember, and the movie didn't explain. Somehow, this was supposed to be the next evolutionary step, or some such thing, but why? And why did Leto seem so confident and at peace with his decision, when later we find out that he sobbed in his sister's lap and asked her to help him die?A lot of the acting is truly dreadful, and seems more appropriate to a stage play than a movie. Many of the costumes look like they came from old the original Star Trek series. And many of the sets were obviously just that ... sets with painted backgrounds.As with the other adaptations of Dune books, too much had to be left out in the interest of time, and if you aren't very familiar with the story, you can easily be left scratching your head.
