Old Dune is kind of trippy view that happened once and I can't imagine it happening ever again, not with that budget and quality actors. Its still most approachable of all of Lynch's work. I like it a lot for sort of nostalgic feeling for the 80s vision of the future like from some pulp comics.
New Dune is completely different beast, can't wait till second part comes. That universe is rich for other stories, tv series etc. which seems to be the direction all major studios are moving to.
