So I just finished Dune and loved it, should I continue in the series? I am worried that it will start to jump the shark and I've read reviews that say as much. I love reading and so it's no problem if I waste time on a bad book here and there, but with so many good books to read and my memories of this one fresh and good, I hate to ruin these memories if the sequels take a turn for the worse. Any thoughts from people who have read Dune Messiah, Children of Dune, etc.?
