There are still some things I am thinking about the handling of.
Some of the changes make no sense to me, but don't bother me (why is Fili now older than Kili?).
Some of the changes seem interesting for the transition to film.
And the integration of the History thrills me to bits.
But the thing that keeps coming back to annoy me is the Elven King paying homage to Thror under the mountain. Because That. Would. Not. Ever. Happen.
