If you notice, most of the people who criticized the book hated chiropractic to begin with -- it's not surprising that they rated the book so low. But that's just their prejudice showing.
This book clearly notes that chiropractic isn't a "cure all" == it is merely (merely??) a way for us to allow our bodies to work properly, the way they were meant to work. It's no wonder the medical profession (and its proponents) fear it.
The book is thorough and easy to read, with plenty of real-life cases to prove the points made. A good companion book is "Chiropractic Works."

The best out there. Once again Chiropractic First is so important for the chiropractor to be successful in practice. This is because this book gives the reasons why a chiroprator is giving an adjustment, which will make patients realize how important it is to correct a subluxation.
