@joyce Agreed. When she learnt of the Dukes death, so broke down. It was an incredibly powerful moment in the book because she has Bene Gesserit control. However, in the film she cried on several occasions and it was totally out of character.
I've not seen a true adaptation of the book yet. The TV miniseries got a lot of things right but it didn't have the budget.
I'd love to see a TV series really do justice to the conversations which, for me, were the real meat and potatoes of the book.
