'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.
The only way to see a movie is in a big theater, on a big screen, with a big bag of popcorn.
It really doesn't matter whether it's the villain or the hero. Sometimes the villain is the most colorful. But I prefer a part where you don't know what he is until the end.
