Query: On the good side, this book could have been worse (but don't know how)

Bemusement. I'm filled with bemusement by the large number of 5 star reviews of this book. This book is improbably bad and I had to abandon it about half way through, going any farther along would have been painful and an unwise waste of time.Other reviews, particularly the one star explain why. This review is just to help lower the star weight and, one hopes, save some hapless reader valuable time and money.
