I liked Boromir better than Aragon. They killed the wrong ranger. ;(
Ahh, but Boromir was not a ranger. He was essentially the Prince of Wales of Gondor.
I thought the way Boromir was shown as falling into sin when tempted beyond his ability to resist, but repenting and redeeming himself by great bravery to be very affecting.
Also the orcs were really stupid tactically, except for the big mean one, of course.
