The first Hobbit: An Unexpected Journey trailer was a great one and well worth the hype it gave the movie. Since then the project has seen an entire movie added on to it, but beyond that we've barely received any new information. With the crazy amount of media saturation that most big movies get, that's a good thing. Nonetheless, this new trailer gives us a much needed Tolkien fix, and it's every bit as awesome as the first one was.
Nice. I'm still impressed that they were able to make the dwarves look so unique, though I'd prefer that more of them had longer beards. It's a minor complaint though, especially in light of how amazing the rest of the movie is shaping up.
