Another question (spoilers):

Why do both Thorin and Gandalf agree that the Rivendell elves will try to stop the quest (and so they must lie about it e.g. academic interest only) and then when Elrond finds out, he's not that bothered.

Why does Balin attempt to stop Thorin handing the map to Elrond, and then as soon as the runes are deciphered he blurts out the actual mission objective  right in front of Elrond?

Yeah, lots of the people are having these conflicted thoughts. It is a letdown after LOTR were so perfect.

Hopefully Radagast will pay off.

As for the long action fight scenes, they could definitely be trimmed, but they did look smoother in the 48fps version. T

Positives: score, Wargs, landscape porn, Thorin, Rivendell, Goblin King, Trolls, Riddles scene, lucious production design, finale was okay, second song
Negatives: almost none of the humour worked, excessive CG, childish tone, cockney villains, bland Martin Freeman performance, Pale Orc too cartoonish, contrived emotional arc, unrealistic action, dwarves indistinguishable, first song

Just came back from IMAX 24fps (after first seeing it elsewhere at 48fps) and there's a world of difference with the panning shots. The sequences where (1) Randagast leads the orcs away, and (2) the breaking out of the mines escape action sequence are MUCH clearer at 48fps. Frenetic action in 24fps 3D is blurry.

Spoilers:
The humour is just as flat in both. The combination of Martin Freeman's understated (even bland) performance combined with the camera lingering on him doesn't work. Four examples: (1) the fainting scene needs to shortened - it's not funny, (2) the scene where Bilbo changes his mind in the morning about joining the adventure is done without any emotion,  (3) the reaction to 'if we win we eats it?' is too long (3) and the scene where Bilbo pulls the sword out of the dead warg and stares expressionless (forever) at the charging wargs. All four scenes need a trim or better take. They could have almost cast Sam Worthington. Perhaps blandness works better for international box office - as its not culturally specific.

Also, I'm not sure if I want a sword that glows blue in the presence of Orcs when it's going to give my location away in the dark. I'd be asking the Elvish Appstore for a refund on that spell.
