Do yourself a favor and go watch the Dune mini series from 2000 and then the Children of dune mini series from 2003. More story, more substance. Unless you are concerned primarily with visuals of course, which is all this movie wins in. The two miniseries are a better depiction of the stories in the books, whereas this film is extremely empty and slow and boring.
Part 2 was pop-garbage, a rip off exploiting the story and other stories to change it completely, where it only expanded on its wasted opportunity of part 1 to make a complete waste of time. It's very difficult to recommend this film and its prequel for anything but 'nice visuals'.
So, your best bet is to read the books or go and watch the two mini-series mentioned above between 2000 and 2003.
