Messiah is just good enough to make you think that the thrid book will be ok... it's is indeed ok. The third book is ok enough to make you think the fourth book will be ok. It's not. It's rotten. My advice: Even though Dune 2 is a good book - it's best to stay off the slide downwards or you'll wind up like me reading all of them and wondering if I could get the time back.
