Dune blew sand.
It was great, except for the "wierding modules", their vision of sardaukar, really gay ornithopters, and the declaration at the end that Paul IS the kwisatz haderach (which, actually, he wasn't) and a few dozen other details.
unfortunately, that really spun the gist of the whole idea of the story and, as i had read the book many times, that killed the whole movie for me.
If I had never read the book, I might have appreciated the movie on its own merits.
