I liked the new Dune. I had seen the older 1980's version and was pretty unimpressed. I have never read any of the books, but when I was in college in the 1970's lots of people read them and all the paperback racks in stores had the books.
One thing I noticed with the new version was that some of its concepts were stolen by George Lucas with Star Wars. This may make some newer viewers see Dune as a rip-off of Star Wars when it was the other way around.
The first Dune movie by David Lynch was a real mess. There was a several part miniseries done later that was more faithful to the book and I thought not bad.
The book is so far beyond any movie or series; very deep, and really ahead of its time. Herbert was making a point years before the oil embargo, that whoever controls oil has a massive lever over those who are addicted to it.
He also made fun of the ‘savior’ trope, where some person from an advanced culture, thrust into a ‘primitive’ one raises them up and saves them; Paul does that, but at the cost of unleashing a war that kills billions (second book), kind of mocking the ‘hero’s journey’ concept while using it.... Worth the read and then judging the movie gets a lot harder.
