They picked a good spot to end part one, but there's little way for it to feel like a complete movie since the rest of them haven't come out yet. After all, this is like three hours for only getting to chapter six(?), albeit with a lot of extra material, invented and canon. Most of the
critics responsible for the bad reviews seemed to complain that it was too long for what it was, so Jay's comment in eechats about ADD's liking it for constant visual stimulation was a bit misplaced.
But the recent Tolkien films have already been under fire for their length, and then criticized whenever they skipped someone's favorite scene in the book, so I'm sure
the Hobbit will survive.
I remember struggling to contain my laughter at people trying to get up to leave at the end of the
Return of the King, only to have a new scene unfold. Some of them sort of half-stood when the credits started rolling, unsure if it REALLY was the end or just a nasty trick.
