I would have gone with you to the end, into the very fires of Mordor
Being that I am an incredible dork, Aragorn's presence on this list was unavoidable, almost as unavoidable as Luke Skywalker's. Even if I wasn't I would include him. Why? Because he really is a great hero. We don't meet him until about a quarter of the way through the first movie but we learn so much from him. At first, when we learn that he was supposed to be king but decided he wanted to do otherwise, I thought he was nuts. But then we learned about his personal problems and the issues he was dealing with and we understood why he would want other plans for his life. It makes it much more satisfying for the audience when we see him put aside his personal baggage and become who he was born to be.
