Query: OK for pop sci-fi, but not worthy of Dune name

This book is OK if all you are looking for is a possible history of the events preceding Dune, but the writing leaves a lot to be desired. It's written along the lines of the Star Wars type books, and comes across almost like a comic book with very cardboard characters. There are too many references to 20th century pop culture ideas (e.g. feng shui, thinking outside the box, etc...), and it attempts to make all the characters fit in line with their representation in the movie.
