"The Dune series is remarkable in that each sequel gets progressively worse until it's unreadable.

The first book is truly excellent. It's mantra on fear alone makes it great.

The second book a very good sci-fi novel.

The third book is merely okay.

The fourth book is sub-par, but still interesting.

The fifth book is a pain in the ass to read.

The sixth book will leave you concerned about the author's health, so terribad is the writing.

But hey, the first book kicks ass!"
