I see there is some support out there for the idea of Arwen going with Aragorn on the Paths of the Dead.
Some support, and even one or two who agree with me that Arwen should have been at Helm's Deep.
The majority, however, do not agree with Arwen at Helm's Deep or on the Paths of the Dead.
Why is this?
Is it because this is a corruption of Tolkien's writing?
Is it because Arwen is simply no warrior, and belongs in no battle?
Is it because Arwen is taking up screen time, when screen time is precious?
I agree that Arwen is taking up screen time in a film that has none to spare.
I agree that she is no warrior (ESPECIALLY not if you go with Tolkien's conception.)
However, people do things for love.
People, do the most dangerous and courageous things for love.
I can see a woman, even a non-fighter (and Peter Jackson depicts Arwen as a fighter) going to Helm's Deep to be with her love in his darkest hour to date.
If Peter Jackson insists on putting Arwen in the film and taking up film time, insists on trying to make us care about this elven woman and her plight, and care about what she does, then shouldn't he have a powerful resolution to this love story he has put onscreen?
Perhaps Helm's Deep wasn't the best resolution - I thought it would have been, and I know Peter Jackson must have thought so (why else would he have filmed Arwen at Helm's Deep? I know he cut those scenes, but he did film them.)
Perhaps the Paths of the Dead are a better resolution, but that road involves all the dangers of the Hornburg, and then some more dangers on top of that.
Can you imagine Tolkien's Elrond allowing his daughter to go off on a road that leads to undead monsters, then to all out war with the Corsairs, then to all out battle with the colossal Morgul Host and Black Captain? (And no, Aragorn had no way to know the Black Captain was dead.)
In the books, Elrond protected his daughter as throughly as any 19th century father would protect his daughter, with all the good and bad implications of that treatment included.
I think that yeah, with Peter Jackson's conception of Arwen, she could be at Helm's Deep and it could work.
I think it should have been done.
I am endorsing, in effect, a severe corruption of Tolkien's character and thinking, and I admit it (but Peter Jackson already has done this.)
I respect the Professor enough to say: Ok, perhaps they should have left Arwen as Tolkien created her.
But they didn't. They altered the character.
If they are going to do this, they might as well have a good resolution to the love story they created between Aragorn and this altered character!
