Meh, Brian Herbert called the 2000 miniseries "the definitive adaptation" back in the day and before that he tried to make his Dune novels consistent with the Lynch movie.
I mean, the miniseries and the children of dune mini series are amazing. A few things get changed, and the budget wasn't always there, but it was very faithful in general, had good acting, and in my opinion they are the best possible adaptations that can probably be made, outside of spending more money for effects. It also didn't take anything from the shity Lynch movie, as opposed to this film which seems to be based more on the movie then anything. As Far as I'm concerned, there is no reason to adapt the story again because the miniseries exists, which is why I'm not really angry at this movie. What does it matter if they keep making shitty Dune movies when I can always watch the definitive adaptations of the 3 good Dune books already?
I think Id care more if there was more I was interested in seeing adapted, but everything after Children of Dune would be almost impossible to adapt, both because it gets ridiculous and it would probably cost too much. Actually, I would like to see the Brian Herbert and Kevin Anderson mid-quels adapted, I think they were called Winds of Dune and Paul of Dune? I actually really enjoyed those.
Honestly, I think that the last 2 Frank Herbert Dune books are worse than any of the Brian Herbert and Kevin Anderson stuff. Heretics of Dune and Chapterhouse Dune are absolute garbage and also weirdly X-rated, for reasons I'll never understand.
