Dunno if it's been mentioned before, but I think the Dune novels could benefit from an even more serialized format.
I'd very much like to see
Dune done in a
Game of Thrones-style TV series.* I guess I'm not sure how long such a show should go on for - I'd like the first four
Dune novels in an ideal world, which would probably add up as three seasons (such a slender thing,
Dune Messiah), but I don't know, maybe there's a way to save
Chapterhouse and
Heretics, either of which I haven't read in almost a decade and only dimly recall really not liking at all.
I guess the problem beyond a lack of closure to the existing Herbert novels as an arc - this assuming, of course, one doesn't just want to adapt the first book - is whether or not a
Dune film would be prohibitively expensive.
*It's a conflict between two great houses, with a focus on the patriarch of one of the houses and his offspring as he moves to a new location... the comparison comes rather naturally, frankly.
