A Dune Muppet Movie would be glorious.
Doubly-so if you can find a way to make it into a musical--which honestly doesn't seem like it'd be too hard.

Okay, I mostly just want to see Josh Brolin as Gurney Halleck having to listen to a Dune-ified, Muppet rendition of 'Getting to know you' from the King and I.
Actually, Gurney Halleck being the only non-Muppet in the movie sounds like a good time in general.
On movie itself
-I don't recall there being anything about atomics in the first movie, and that seems a shame. They become a bit of a sudden blessing from nowhere coincidence in part two when they didn't need to be. Gurney being alive is already kind of a coincidence, having a little more 'setup' to Atreides atomic weapons would've been nice (I absolutely forget how/if the book does anything different, though).
-See what they were going for and even kind of like how the film shows Paul the awwshuks freedom-fighter, his mother the manipulating Bene Gesserit, and Chani the skeptical-native who's still drawn to Paul, blah blah blah there's all kinds of competition between mother and lover there that's all appropriate...but...Zendaya and that damned 'Chani screaming cliches at an entire room full of people' scene combine to make me just roll my eyes.
-Kind of like the book, as I recall, it does similar cliche character's-reflection stuff between Feyd-Rautha and Paul, but whether it's not being distracted by Zendaya's Zendaya-ness or just something else it's not nearly as distracting, despite being very not-subtle in some of the same ways.
-I'm still surprised at how absolutely little part Walken played. The Emperor is just not really a force--and while that seems to have been kind of intentional and maybe fits the narrative...Was expecting a bit more to that entire character. Especially with Walken playing it. Just seems like a wasted opportunity.
-Like the first it does such solid job worldbuilding and presenting that a long run-time doesn't actually feel that long.
-Stilgar kind've got relegated to background character in favor of Chani...Not sure that's a good trade, but I'm very biased so...
-Part three (Messiah, presumably) when...Or do we need a whole film dedicated to Glorious Fremen Jihad? That could be fun, if not exactly artsy...
