I liked this film.
But I'll start off with one of it's major flaws, and it's one that's it's pacing and structure. The film is basically a series of unrelated adventures that the Dwarves get into as they make their way to Erebor. They walk, they fight some things, they walk some more, they fight different and unrelated things. It all feels a bit (and ONLY a bit) disjointed.
Of course, the thing with that is, that's exactly what the story of The Hobbit is. It's not Peter Jackson's fault, and it's really not Tolkien's fault either. It's mainly a symptom of having the book split into parts, so you get all the small adventures but no actual resolution of story.
But the important thing is, all the little adventures, the trolls, the goblins, the wargs, Riddles in the Dark, etc. are really really good, really well made and really well put together, and a pleasure to watch.
Radagast was awesome. I love Radagast. In the books, I loved Radgast. I loved Radagast here. He's mad and all about animals and helps hedgehogs and is fantastic. Can't get enough Radagast.
And all the other bits of filler, the flashbacks, the White Council - again they all felt slightly out of place... but were all so good you didn't really care. And they even mentioned the Blue Wizards. Awesome.
I'd say the main problem this film has is it's lack of an ending, which was kind of unavoidable really. They did try and give the film an arc of it's own, with the whole thing between Thorin and Azog, but that didn't really work...
Oh, and the eagles didn't talk. Fuck that.
