Hurrah for Boromir the Disco King!
Since the Downers before me have mentioned most of the reasons to love him, I will mention the one that appeals to me the most...
Boromir totally loves his brother, Faramir. He does not rub it in his brother's face that he is the favorite of his father and of Gondor as a whole. He even suffers himself to journey all the way to Rivendell in spite of his father's disapproval, just so Faramir does not have to.
Who would not love someone who treats Faramir that way?
