Query: The worst Manga Mania book yet!

Yes millions of anime fans hate his Manga Mania because he can't do the art right and they hate his books because he hires people to do the art for him but........THIS IS THE WORST YET! Last year one of my friends showed me this book. I felt like laughing Chistopher Hart really doesn't know what anime is! He hired the worst people yet! There is like only two or three good artist (one was the one the one that did the front)and the rest of them were terrible.Most of the book is terrible mabye like ten pages are good but the rest how sad! Even if this books cover looks good don't judge a book by its cover.
