Yeah, the trolls in The Hobbit are kind of jarring when compared to LotR, but I consider them their own thing. Though it isn’t identical, the dialogue is pretty close in spirit to what’s in the book, and I think the book scene is pretty funny. I found the scene as released in the film to be horrifying – the butt-scratching and egregious snot just made me cringe. Without it, and accepting that these are just not LotR trolls, I personally think some funny was recovered.

It seems like it might be possible to make a cut where our heroes stumble upon the trolls already turned to stone and still raid their stash to get the swords. More aggressively, one might be able to cut the scenes with Elrond analyzing the swords and the goblins freaking out at Orcrist. That leaves Sting, which is Sting – cuttable, but a great loss. One might be able to trim the scene of Gandalf giving it to Bilbo to make the context obscure. Maybe he just happened to have it lying around in his wizard stash.

That’s not this edit though.
