You will definitely see a good share of negative comments on this book (check Amazon) but it's dependent on what your beliefs are. As Christians we believe in the creation view vs evolution. Naysayers on this book most likely believe in evolution and the science behind it. Unfortunately people are turning their backs on the Bible and looking more and more to worldly/man explanations. In my opinion this book is a good child friendly explanation from a Christian perspective on dinosaurs and how they fit into the Bible.
I think children and adults today need to get a Biblical perspective on questions like: What Really Happened to the Dinosaurs? This book with that very title helps explain a puzzling scientific question on a child's level. I hope to buy other Christian books in the future similar to this one to add to our children's collection at church, and to give to our grandchildren to help them better understand these issues.
This product was excellent in explaining the dinosaurs and how they fit regarding creation and the ark. My kids (7 & 4) enjoyed it. It does not go into detail about the different kinds of dinosaurs but did answer all the questions I had about how dinosaurs fit in Genesis.
