Query: Terrible Book

I am a firm Christian, mostly conservative in my beliefs. I am also a good reader. As I skimmed through this book, I was shocked at the number of mistakes the author had made. He was clearly a poor researcher. I have never watched or played Pokemon, so I don't know how many mistakes he made in that part of the book; however, as I read the Harry Potter section, I simply could not believe that this man was making so many claims about the series, using so many big words and sounding so official, when he couldn't even get the author's name right!!! He wrote that "J.K. Rawlings" was the author of a series about people called "Death Enters", and that a "Dark Mask" appeared in the sky. I don't know about you, but I can't take seriously a source that cannot even accurately name the things he calls evil.
