It also shows that Jackson perhaps just shouldn't be adapting The Hobbit at all. I've been jaded on those damn project for months and adding in characters who previously didn't exist in Tolkien's narrative at all is the final nail in the coffin as far as I'm concerned.
The Hobbit is a simple tale and it's held up as is for almost a century despite the changes in our world. The story is Bilbo, Jackson! He's the heart of the tale! Get a clue!
And of all the things they had to add, it was a token Xeno ripoff warrior chick. *sigh* On top of that, we still don't have a Bard, which means the role of killing Smaug has probably been given to Legolas or HER. On top of that, they've also cast young, handsome men as the dwarves (God, why?!).
Ugh, I don't know why they're even bothering with the pretense that this is a Hobbit movie anymore. It's not. I was dubious about the White Council, but the presence of Itaril is just too much. Between the added Itaril and the White Council and how they'll inevitably drag out the campaign against Sauron and the Battle of Five Armies (Helm's Deep was an entire hour of Two Tower's running time, and the siege of Minas Tirith was even longer) I just don't see how Bilbo even fits into his own story anymore.
