I have much of the same thoughts. Sir Peter Jackson nailed it with The Lord of the Rings ("My friends, you bow to no one.", "I can't carry it, but I can carry you!", "So do all who see such times...") with a few complaints. (Aragorn and Frodo's combined is so miniscule when compared to the stairs in Moria, why would leaning forward make a lick of difference?!) And Howard Shore pumped out some of the greatest motion picture soundtrack music ever. Like, legitimately in my top three. It was just a fantastic overall movie.
But not The Hobbit. The music was generic (except the sweet dwarven theme used in number 1), the runtime stretched, and the emotion missing. It was TLOTR but worse in every way. One good thing, however, did come out of it: The Last Goodbye. I dare you to listen to that song without tearing up.
