Query: Entertaining, no Dune

Entertaining sci-fi novel for readers who enjoy the genre, very disappointing for someone hoping to relive the "Dune experience". House Atreides completely lacks the depth, complexity and intensity which made Frank Herbert's books thought-provoking as well as enjoyable. While I appreciate the authors' effort, I don't plan to read the other planned Dune prequels.
