Re: The Hobbit: An Unexpected Journey - Grading & Discussion (Spoilers
I'm kinda surprised by all the Azog criticism. He may not be in the book, but he's still an absolutely badass villain with an awesome design, and something I think the movie really needed.
Technically, he doesn't really appear in the book, but he is mentioned in The Hobbit
and in the appendices for The Lord of the Rings
