So I was rewatching Jackson's "Hobbit" film trilogy (I only got up to the death of Smaug, which starts out the third film).
It's kind of a frustrating watch, because there's some great stuff + some stupid stuff. I'd always be curious too, to see which parts came from the Guillermo del Toro script(s).
Some of the casting was just impeccable, honestly (Thranduil, Bilbo, Gandalf, Thorin, some of the dwarves -- Dwalin is actually Graham McTavish, who has the same kind of presence in HotD when he's been on it). Others I was indifferent to. I wish Beorn (in human form) had been more compelling.
There are moments in these films that are just pitch-perfect, although Jackson had setup for some. For example, the Unexpected Party at Bilbo's house -- and I will say too that they managed to set the lyrics to new music that actually makes sense and is evocative. Or the Riddle Game with Gollum. (I actually could feel bad for Smeagol and understand why Bilbo felt pity for him.) Or when Bilbo and Smaug first meet -- that scene (before it drags on too long because Smaug likes to talk too much) is absolutely terrifying.
I was indifferent on the Kili / Tauriel love thing. I mean, Kili is cute, and there are far worse things in the film that obsessing over this newly introduced cross-kin love affair.
While we know Gandalf and the White Council stormed Dol Guldur to drive out the Necromancer (aka newly reforming Sauron), most of this version is shite. One thing that was right was when Gandalf and Sauron face each other, it actually did feel like force of power meeting force of power versus two guys casting magical spells or beating on each other with sticks. I haven't watched conclusion of this sorry chapter in the third film yet, but it's one of those things where Jackson's fleshing out the scene is worse than imagination, it feels rather lacking because he has trouble with non-literal presentation. (Hence, all the CGI versus suggestive film making.) The whole storm giants thing shortly before the company is captured by goblins was way too much and almost ridiculous in the various catastrophes they almost caused to the party -- it was just an off-hand comment by Tolkien, generally, in the text, and could have easily been excised or not mentioned. And he makes them literal stone monsters.
We also get Legolas behaving like a god with some of the crazy shit he's doing in these films -- and I know I haven't even gotten back to the craziest part at the end of Film 3 where he runs up the debris of a collapsing tower -- but geez. He's Thranduil's son, sure, but he's not a superhero.
Which leads to probably the biggest complaint in that Jackson clearly padded out the story to get three films out of it. He added the whole Azog and Bolg bit as ongoing villains to give a clear villain to the unfolding story, and this gave additional material. Sequences that were not fraught with a lot of detail in the book or were mostly uneventful have instead been "spiced up" to provide additional action pieces (the escape from the Great Goblin, the barrel ride from the Elf King's dungeons, the whole fight between the dwarves and Smaug before the dragon flies to Laketown, the inclusion of the Dol Guldur bit which had way too much time spent on it, etc.) I understand why maybe he wanted to amp up conflict between Smaug and the dwarves -- Tolkien kind of sidestepped it all, the dwarves want to kill Smaug and have spent all of this effort but then never actually fight Smaug, who is killed when he attacks Laketown. But it honestly feels like a lot of needless material was added in order to make three films rather than two.
So some of it is really decent, some of it is average, and some of it is eye-rolling. At least Martin Freeman and Richard Armitage and Lee Pace are great.
