I read Dune and the follow on books (Dune Messiah, Children of Dune, God Emperor of Dune, Herretics of Dune and Chapter House Dune) a long time before the first movie was made in 1984. I found them very interesting, if a little weird in places.
When I first heard that they were planning to make a movie I was excited.
Sadly what they produced was very disappointing. There is a lot of internal dialogue in the books which was poorly handled, slowing the pace of the original movie. Nor was there sufficient time in one movie to introduce the society in which the story was set.
I haven't seen the 2000 Dune mini-series & it's 2003 Children of Dune sequel or the 2021/2024 two part re-make of the first movie.
I guess I should give it a go, but I don't want to be disappointed again.
