I first read the 6 original Dune books in the late 80's, early 90's and always so far abstained in reading the sequels or books by the son. But a new movie is coming soon, the trailer is quite good, so I reread all the series and then got trapped by the heavy marketing the son does for his two sequels on the Kindle edition. I really shouldn't have. I read through them in a few days (it's so vapid that if you read the first and last sentence of each chapter, you get the drill anyway) with a sort of morbid fascination : how can the heir of such a great mind release words with such abysmal lack of style, depth, interest, plausibility, consistency with the previous stories ... And it took two to do that ? This is the shameless exploitation of an undeserved legacy. Stay away if you ever loved the original books !
