Boromir:
I will find no rest here. I heard her voice inside my head. She spoke of my father and the fall of Gondor. She said to me, even now there is hope left. But I cannot see it. It is long since we had any hope. My father is a noble man, but his rule is failing. And then our... our people lose faith. He looks to me to make things right, and I, I would do it. I would see the glory of Gondor restored. Have you ever seen it, Aragorn? The white tower of Ecthelion. Glimmering like a spike of pearl and silver. Its banners caught high in the morning breeze. Have you ever been called home by the clear ringing of silver trumpets?
Gandalf gets a lot of very authentic lines, and Saruman - well, he sounds right. Everyone else has sort of a mixture of book-lines and movie inventions.
You know, the more I hear and see of Boromir the more I like him. He seems to represent Everyman. We want to do things right and we have noble goals and aspirations, but then our fallen nature gets in the way and mucks everything up.
Boromir was in torture and torment until he recognized and pledged fealty to Aragorn (in a Christ-like sort of way). Then he was able to die in peace, restored.
Personally, I blame it all in Denethor. He put WAY to much weight on Boromirs shoulders. Looks like Denethor pinned the survival of all of Gondor on the ability of Boromir. And Boromir, being the dutiful son, took up the burden as his own. Reminds me of Robert the Bruce and his father in Braveheart.
