Yes, Bofur was a good character, and one of the rare cases where embellishing on the book created something decent, in my opinion. I liked the dynamic he had with Bilbo, sort of big-brotherly teasing with an underlying protectiveness. Martin Freeman was wonderful, very sympathetic. One scene I found really moving was the moment he caught up with the dwarves carrying the signed contract (I was a little disappointed he didn't get the oversized green cloak and hood from the book afterward: for some reason those items always seemed important in my mind).
I didn't care for Barry Humphries as the goblin king. I suppose some might have found him entertaining, but to me he just seemed very out of place (a friend of mine called him the film's "Jar Jar Binks" and I agree). I shouldn't entirely blame the actor: his lines were dreadful. As for the battle that followed, it looked like something out of a roadrunner cartoon. The goblin scenes actually made it difficult to for me to fully enjoy the neighboring "Riddles in the Dark" scene. The latter was on a set that wasn't nearly dark, or large, enough, but Freeman and Serkis could have probably managed to be convincing in the produce department at Wegmans. The writing still wasn't great, with too many dual-personality jokes for my taste. I'm just not a fan of Boyans and Walsh, and never will be.
I really loved the dwarves' song* and wish there had been more new music. I'm actually sad that neither the elves nor the orcs sang. Tra-la-la-lally's are optional, but, well, you know what they say about elvish singing, in June, under the stars.
One really minor thing that that annoyed me far too much: why does Galadriel need to strike a dramatic pose at all times while having a conversation? Surely they could have come up with slightly less corny way to make her look impressive. Yes, I know she does a bit of that in LoTR, but it isn't as extreme.
I'll just stand on this ledge here with my back to you all so everyone knows I'm special.
I wasn't really happy with the Necromancer (who looked like something out of a sci-fi movie), but mostly liked Radagast, though his costume was over-the-top. The embellishments to the plot surrounding Azog weren't really objectionable: of course PJ wanted to create more continuity and at least Azog doesn't do too much that the generic goblins didn't in the book.
I suppose I sound too critical. I certainly found more to dislike here than in FoTR, probably because more was invented/padded, and several scenes seem to have been there because PJ was going down some kind of "successful movie formula" checklist. I'm still looking forward to the next one. A friend I went with, though, said that she felt like she didn't need to read the book after watching this, which just... *sigh*
What do you say to that?
*Edit: the version in the movie, not the one at the end.
