|Don't worry! You can trust me!|
The truth the movie tells us about Peter Jackson is that he has become a Gollum. He thinks "The Hobbit" is his to do with as he likes. Where he hews to the story the movie is fine. When he hews "The Hobbit", cutting from and adding to as he wills, it's a mess.
To be fair, some of the additions work quite well. The council at Rivendell with Galadriel and Saruman gave a sense of import and danger to the journey. I also liked the prologue with the Ian Holmes' Bilbo and Frodo.
However, having Azog, "The Pale Orc", survive an earlier battle to be the enemy of Thorin Oakenshield brings several changes to the story, and not for the better. As other have said, it is no longer simply "The Hobbit". It is now a prequel to Jackson's "Lord of the Rings" movies. It is his precioussss, not ours.
