I recently rewatched Villeneuve's Dune in addition to reading the books for the first time (after being a long-time fan of Lynch's take) and I kept thinking a TV series is what it needs. It's hard to imagine it following on from Villeneuve's film given they've dropped so much from the books although I think it can be done. What would be incredible is a Rings of Power-style big budget TV adaptation which would make room for adapting the more fantastical stuff from the sequels as well.
