Yah, memes float around the world of ideas. I think that is why “Dune” is less offensive than “The Golden Compass” appears to be . . . “The Golden Compass” is apparently designed to be a pedagogical sneak attack on Christianity while “Dune” is a more organic creation from the ideas that Herbert had incorporated into his worldview; it wasn’t intended to be a lecture or an attack.
It seem to me more out of the 60s counter culture ethos of liberation: sexual liberation, personal liberation & hedonism (do it if it feels good), moral relativism & value creation (the real Nietzschean deal), etc. It's the “Don’t let authority figures like the “Establishment” or Church tell you otherwise, man” indoctrination hippie kit, but for kids who like LOTR, Narnia and Harry Potter. However, if it was truly Nietzschean the movie wouldn't want converts or students... Zarathrustra certainly didn't. As well, Nietzsche wanted aristocrats not hippies. This seems to be more about the continuing rise of secular liberalism of the left at the expense of the church. A liberation theology first started by Marxists and adopted by hippies and Hollywood.
