Courage, honor, nobility... all there with the wind blowing his hair while he slowly takes out his sword. Even if it is two gazillion versus 1, you (almost) feel sorry for the two gazillion because it isn't going to be a fair fight.
The other thing about that scene is Legalos. Arrow in head of Urak Hai then fired. Then the three arrows fired in rapid succession, each finding their mark. Wow!
Boromir's death is fantastic. I think Sean Bean did a great job showing Boromir's lust for the ring and his commitment and love for the hobbits and the rest of the fellowship.
I think this is one of JenB's favorite scenes too. ;-) He has a similar look on his face when he says "Let's hunt some orcs". Oh baby baby.
