I didn't read your whole post, mostly because I thought I was in the development dune thread, not the review thread, and as soon as I realized I stopped reading, but I did read the first paragraph and I strongly disagree. The Harkonnens are over the top *stereotypically* evil in the OG novel. That's why Lynch had to go to the point of heart plugs, they are already so bad in the books. The Baron is a notorious, incestuous pedophile & rapist. His older nephew murdered Gurney's sister and tortured him with a whip, Feyd poisons opponents with glee in front of audiences of thousands, and attempts to assassinate his own uncle. They're so notoriously evil a regular Mentat won't do they have to hire specifically "twisted mentats" from the tlielaxu to help manage their evil plans (although that's later revealed to be a fraud, mentats aren't "twisted", they're just psychos put through regular Mentat training).
