The belief in some being who can be the judge of all human matters is a very comfortable one - all wrongs will be righted and all rights will be rewarded.
'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.
