I strongly disagree. I found this book made excellent points. You can get an overview of those points at the Heath Brothers' website. But you'll get the most out of this book by reading it. I also found it entertaining.
I don't mean to disparage this reviewers' opinions, but I would hate for someone to refrain from buying the book based on this review. Instead, visit the website and get a feel for what the book is about - you can even read the first chapter there. I plan on using the principles in my marketing and copywriting.
