'3:10 to Yuma' was one that I just kept on talking and thinking about after reading it. And I think the reason is because, like in most Westerns, you have the very clear-cut bad-guy/good-guy, however, as the movie progresses, you kind of see that it's a very fine line that divides these two.
I remember when I was in college, people told me I couldn't play in the NBA. There's always somebody saying you can't do it, and those people have to be ignored.
