SPOILERS: "The eagles are coming!" at the end of Return of the King (or halfway through it in the book) I think was meant to be a reference to the Hobbit, where (I think) it's the last thing both Bilbo says before he is knocked out and the last thing Pippin says at the end of the chapter for the battle at the black gate. /SPOILERS
Anyway I saw it in 3D HFR (not actually a big fan of 3D, but I think that the HFR makes it better), looking forward to seeing it again in 2D at some point. As you might know from me posting in this thread I'm more than willing to take the films as they are and think there's no reason why they are inherently bad just because they are "3 films out of 300 pages!", but I think there are a few things in this film that could have been done a bit better. I actually found myself wondering if the extended edition might be a big improvement this time (I know, heresy to all the people that think being long is the problem) for a couple of specific issues:
SPOILERS
1. I try not to go out of my way to seek out info or overanalyse trailers for films, but in this case I had seen an advertising image of dwarves cavalry charging down the hill on mountain goats, which I thought was a really cool idea. I don't remember seeing that in the film (you might be able to spot some mounted dwarves in the army), which was a little disappointing but not a big deal. But then when Thorin, Fili, Kili and Dwalin want to travel up the hill, Throin suddenly grabs one of those mountain goats from the battle and the next shot all four of them are riding them. Would have made a lot more sense to make sure we had seen these goats before that, and I'm hoping that will be in the extended...
2. So little was seen of Beorn. The fact that he came in on an eagle in human form and jumped off, changing into bear form, was pretty cool, but I was very disappointed that that was the last you see of him in the battle. I don't mind all the stuff in the battle that isn't strictly mentioned in the text (since not much is really described at all), but the basic story beats of the battle in the book are "Elf / human armies besiege the mountain, dwarf army arrives and they face off for a bit, army of orgs and wargs arrive so dwarves / elves / men team up to fight them with Thorin and the rest leaving the mountain to help, it looks bad but then eagles and Beorn arrive and turn the tide. Beorn even charges in and kills Bolg (who's the leader of the goblin army in the book) and carries off injured Thorin to safety (he was injured fighting "Bolg's guards"). I don't think it was necessary that Beorn kill the leader of the army (or even Bolg, who was more of a second in command here), but I think it should have been made much more to leave the impression that Beorn had a big impact on the battle and helped turn the tide. Plus seeing a giant bear fighting is always good and he was underused. I think I saw somewhere that Beorn's role is shown more in the extended so hopefully that does something to improve that.
