Totally agree, this looks like it'll be missing everything that's weird and wonderful about Dune.

Lynch's Dune can be bewildering coming at it without the context of the book, but that aspect of it is frankly just something you get used to with Lynch's works, and like you said its filled with so much oddness and detail. The hulking Heighliner spacecrafts, the mutated ghoulish guild navigator, the fascinating cave-like imperial palace set, the manic cyst-covered Harkonnens. I've never understood why it gets a bad rap, I think it's a hugely underrated film that did a wonderful job capturing the strange universe of Dune.
