[Hey everyone- first post; great forum.] I remember that the goblins from the original Hobbit movie scared the bejeezus out of me as a little kid. But I always loved that sense of darkness, in movie and book, and how it contrasted with the camaraderie between burglar, wizard and dwarves; the feasting and merriment in Hobbiton, Rivendell, and Laketown, etc. I could picture the scenes of the Misty Mountains as having similar rapport as was seen in the Uruk-Hai scenes from Two Towers, slightly humorous but with a distinct, edgy, and dark character to it.
Also, and please correct me if my recollection is lacking, but I remember reading in either The Hobbit or LOTR that the fact that the Goblin-king was killed by Gandalf invisibly wielding Orcrist in combination with their defeat at the Battle of Five Armies, caused a great scattering and weakening of all of the Misty Mountain goblins. This, in turn, is why I had always envisioned that the orcs of Moria, being beneath the Misty Mountains, appeared similarly leaderless and scattered.
Overall, in terms of director's vision, The Hobbit, I think is infinitely more filmable, because it so much more linear and direct of a storyline. The devil will be in the details as many seem to allude to and their thankful transition to a two part "all Hobbit" movie will enable many more of those details to be fleshed out.
