Dune is basically a political drama in a sci fi setting. Frank Herbert wrote a story about scarcity, destruction of nature, and political corruption. He was extremely interested in ecology. Spice was both a comparison to oil, and to clean water.
This series, while not completely boring, doesn't have any of FH's inspiration, it doesn't give a shit about the environment or humanity. The sisters in FH's Dune were sifting for humans, KJA's sisters are pushing the boundaries of what it means to be human.
Kevin J. Anderson is most famous for writing in fictional universes that other people created, Star Wars, X-Files, etc. He doesn't seem to have the chops to create his own settings with lore he creates himself. His contributions to Dune are bland and trite. You can tell when he attempts to write deep thoughts for his characters, they are dumb compared to the words and thoughts FH wrote for his characters.
