This is really something I want to get off my chest. I admit, it has been awhile since I read the book last time (I just bought the English version though, so I hope I get the chance to read it before the next time I see the film
) but even so I felt like too many times I asked myself: "was this in the book?" or just said: "this wasn't in the book". For example the story between Azog and Thorin (this I checked) wasn't in the book, and was even changed so it conflicts both The Hobbit, by not being in the book, and Silmarillion, by changing the story of the Battle of Azanulbizar. Luckily I really like that story in the movie, so it wasn't a disaster. And from here I can get to my other minus, which is the adding of unnecessary action scenes. I would have rather seen some scenes where the movie would have introduced some of the dwarves more. The story of Azog and Thorin is there mainly because of the action.
