Query: Unfortunately...

...Brian's writing style is not quite the same as his father's. I've only read a couple of the Dune books, but I've read enough to be disappointed by this. I agree with most of the criticisms listed here. The characters are shallow and their behavior often idiotic. The plot is predictable, and cliche in many places. It reads like a kid's Saturday morning cartoon series.
