Query: I want my money back

This book was a waste of money and will be donated to the Goodwill soon. The book is unorganized, jumps all over the place, repeats its self too much, spends way too much time on how things look today, is written in a way that is uninteresting and confusing and the computer graphics are horrible! When I say horrible I mean they are an embarrassment to the publisher. It's sad when the old Prehistoric books from the 60's and 70's put the new stuff to shame. What ever happened books illustrated with real paint rather than is computer looking plastic crap laid down upon present day scenery rather than how things actually looked 10,000 years ago?
