I'm not sure what you guys were expecting after An Unexpected Journey and even the LOTR trilogy.
I completely agree. Frodo and Sam in Osgiliath? Arwen rescuing Frodo? Heck, elves in HELMS DEEP?!
But I loved the movie, and I thought the deviations made were in spirit with the book.
Agreed. I would say the romance is probably the least faithful addition to the movie. But the rest of the changes make sense, to me at least. And in fact, adding Bard to confront Thorin during the town square scene really energized that part of the movie, in my opinion.
A few things that did stick out to me about both movies that I do wish they kept from the book. In the first movie, I wished they went through with having Gandalf trick the trolls, as I loved that when reading the book. And the Mirkwood forest parties would've been awesome to see and it would've made more sense as to why Thranduil imprisoned them in the first place.
