Definitely Legolas if I had to pick, but Aragorn and Boromir would be close seconds.
Now if we're not basing it on who we think is the hottest, but rather who we like from a purely character standpoint...probably either Gandalf or Sam.
The Hobbit coming out has me thinking about LOTR again, and I was wondering who everyone's favorite was?
I just love Dumbledore and the way he shows up to save the day! Just kidding, Gandalf is wonderful. Gandalf the wise. Fabu since of humor and he knows how to party. To bad he's not real because I would just love him to come to one of my birthday parties. Fire works like his would make any party go from awesome to epic.
