The thing I find appealing about Dune is how WEIRD it is. There's depth too, but it's weird and it really lends itself to all sort of styles and IMO they all kinda work.
I’ve started showing my kids, Herculoids, thundar the barbarian, he-man, and other sorts of just really weird old cartoons. There’s not a lot today that’s being produced. That’s just fun and weird and gets the creative juices going. There are a few weird kids books too like the skull and the queen in the cave that I highly recommend. Culture quickly defined by what has already been created could definitely use a shot…
On the less weird, but still interesting side there's what's known to English speakers as Adventure Box - it's a translated version of the French monthly magazine J'aime lire which is published since 1977.
