He's a total wimp.
I've been reading the later Dune books. There's about twelve of them now, and I checked them all out of the library but couldn't make myself go on reading them after about four. They're pretty bad. I could kick Frank Herbert's son whosis, and I could punch Kevin Anderson his cohort-in-writing ... they should never have continued the series. Never, never. Owww.
Yeah, those books are dogs.
Herbert and Anderson have an amazing ability to take what originally was important and epic, and make it small and petty. Alas. I guess that's mostly what I don't like about the books. They aren't epic. The characters are petty. Also, and this is the real pity, Frank Herbert's mastery of dialogue and setting within scene would make any lesser writer look bad. He was almost as good as Dorothy Dunnett, and that's the highest praise I know.
