I understand that no movie is ever just like the book. However, the movie shouldn't casually discard key premises of the book the way this one does. I think Lynch's decision to convert the Bene Gesserit fighting techniques of the book into "weirding modules" that shoot death rays ultimately cheapened the entire story.I could live with the weird visuals of the movie if they had been made to serve the purposes of the book, but as it is, Lynch went too far afield.
