Obviously, I disagree with everyone about most other aspects of the movie. It's not a big issue. I'll just avoid the rest of them.
They didn't? I thought movie elf snootiness changed the whole character of the Elves as a race. Am I the only one bothered by this? :) Outside of Arwen (she can't be snooty towards Men if she wants to marry one), Legolas (he can't be snooty if he's joining the Fellowship), and Galadriel the Elves with their "men are weak" attitude and always looking down their noses (I keep thinking of Haldir telling Aragorn to get his muddy feet off the forest floor) come off looking like a bunch of stuck up jerks. You'd think an immortal people would have time to learn the wisdom of humility. :)
Actually, I think giving Glorfindel's part to Arwen was a feminist pander. I don't think Elrond would let his daughter go running around with the Nazgul on the loose. But I do think she needed an extended role to understand the Eowyn bit.
I enjoyed the movie and just realize that it can't be exactly like the book. I'm happy with the job PJ did. Of course if the choice comes between the book and the movie, I'll take the book any day. Perhaps it would have been closer if it was produced as a serial instead of a movie.
