Query: DO NOT BUY THIS BOOK!

Marvel Encyclopedia: The Hulk is one big let down when it comes to the Marvel Encyclopeida series. The author, Kit Kiefer does not take the subject seriously. For every fact he states about either the comic, tv show or movie, he makes a sarcastic comment to go with it. He admits that he is not a fan of the Hulk. Overall this book is a campy nonsense look at the history of the Hulk. I really can't see comic fans or even hardcore Hulk fans enjoying this book.If you are new to the character of the Hulk (because of the new movie) and want to read about his history, you're better off passing on this book.
