When Radagast mentioned the Necromancer and Dol Guldur, Gandalf acted incredulous, as if he had never heard of any such threat before. This was bizarre, considering that the evil that the Necromancer represented was the very force that Gandalf had been sent to Middle Earth to find. For him to not know what Radagast was speaking of weakened his character. As for his actual appearance at the fortress of Dol Guldur, this was yet another one of the new elements that Peter Jackson created. It appeared that it was included to provide an explanation for Gandalf not meeting the dwarves at the Lonely Mountain, but this was unnecessary; Gandalf disappearing and reappearing are part of his nature as Gandalf the Wandering Wizard. Though it did add a cliffhanger element for the upcoming third film, it was yet another deviation from the original text that took away from Tolkiens original work. The original story was good enough in itself by having Smaug as the primary antagonist; adding the element of the Necromancer (read: Sauron) was simply done to tie these films to the Lord Of The Rings. As if viewers really needed to be reminded of The Lord Of The Rings so much. The Hobbit was a story that couldve been just as good without so many connections to Tolkiens magnum opus.
