I am very picky when it comes to movies made from books. I seriously disliked the Lynch version, but then I don't like much of anything he does. A second part to the latest version is due out this year, I'm withholding judgement until it gets here.
The books are philosophically interesting. Herbert has created a fascinating culture and ecosystem. The primary influence on the people that live on the planet "Dune" is Islamic, the primary influence on the ecosystem is a planet-wide desert inhabited by giant worms. That description doesn't do the book justice by a long shot.
The other books are an alternate history trilogy about a war between the United States and Japan in 1910, and its aftermath. The other is a historical novel set in the Revolutionary war. The first three sold well, maybe because everybody was locked inside by COVID. The other two haven't sold as well, which is why I slip in plug when I can. I invented a church for "Armageddon's Disciples" and I've started blogging about that process. See jeffthomasbooks.net
