I don't think I could get through all 6 books again. I did read all of the prequels and "Dune 7" but they were utter crap (not written by Frank Herbert but based on his notes).
Dune, Dune Messiah, and Children of Dune are worthwhile. But the sex-witches-fleeing-the-machines combined with everybody's a Kwizatz Haderach got a little tiresome. (I now picture Oprah gleefully shouting, "You're a Kwisatz Haderach... and you're a Kwisatz Haderach... everyone gets to be a Kwisatz Haderach!"
