I haven't read the book, and that's probably why I wasn't enthused with the movie. It was very slow, and if I hadn't watched a YouTube about Dune beforehand, I would have been very lost. The movie does explain a lot for you, but it breaks it up throughout the movie. So for things to make sense, you probably have to watch the movie more than once to get it. If i didn't know already, I'd still be wondering what the heck the big deal with spice was about anyway. Honestly I liked John Carter better
