A thought on The Desolation of Smaug

Its stunningly unfaithful to the book. He stuffs as much of Middle Earth Arcana into the story as he can.
I suppose Jackson realizes he is never going to get to film a story about Beren and Luthien, or Turin Turambar, and so incorporating as much of the myth of the LOTR universe as he can, even if it fills “The Hobbit” to bursting, is his way of getting the next best thing.
The movie feels a lot less schizophrenic in tone than Unexpected Journey, though.
