Query: Disappointing

As one reviewer has already mentioned, this book is god-awful! I felt like I had learned nothing new, nothing insightful about the program, not even a fun read. In fact, Fred Freidberger's "All That Glisters" is more entertaining. And the reviews of each epidode are terrible! Talk about brown-nosing! Even the episodes he doesn't like, he has something good to say! Hopefully, this book will immediately disappear, and demand for it will never come...
