I know, I feel like Jackson has to somehow make everything overt and concrete; he really didn't know how to work with suggestion and insinuation very well in some parts of the picture. (You'll hear me bitch about this in some other parts of the film where I just felt like powerful scenes from the book were ruined... such as the Balrog, which like I stated the other day looked like a video game boss rather than some larger-than-life demonic spirit.)I still can't get over how dumb that was. And don't get me wrong, I adore these films, and especially the first, and though I can find things to be critical about, I think all three are fantastic achievements in so many ways. But that bit was just so stupid and cheesy. I remember having a total WTF moment when I first saw it.
That scene is very powerful, especially for Galadriel's character, and he just clubbed it to death like it was a baby seal and he an Urukhai. There are other ways of being dramatic without slapping electric bolts and voice reverb on someone... especially an elegant elf queen who has been around since the First Age. Jeeez.
The Arwen race to the ford with Frodo bit is just fabulously powerful. So beautifully filmed and just brings her out as a character. It was one bit I felt I "should" have disapproved of, being a bit of a purist, but I loved it.
She didn't look "terrible and beautiful," she just looked .... crackly and freaky-weird.
(I wonder how Jadis will be handled in The Magician's Nephew, now that I'm thinking about it. She's kind of the epitome of who Galadriel was tempted to become.)
I think this is also getting back to my complaint about "magic of being" versus "magic of doing." A lot of the characters in LotR are powerful because of who they are, not necessarily what they do -- it's power rooted in their nature and being. Galadriel can speak and command (although she lets Celeborn rule) because of who she is, not because she had to cast some spell per se that would come with a bunch of prerequisite lighting effects, etc.
