No Country for Old Man is awesome because of it's ending, in fact the ending is why the movie is one of the best movie. What No Country is about is not about the killer, it is not about the guy who gets the money, it is not about the shoot outs or the wife. No Country is the story of Tommy Lee Jones, and despite how lame this sounds, the fact that there is no country for old men.
What No Country is about, you wont get from the awesome action bits, but from the dialog and the characters actions. It is about that our world is too fast pace and brutal. When we are young, we are intrigued by it and may even join in on it. (See the guy that stole the money) However as we grow old, there is no place for us. It is not because society changed, it was the same when they were younger, but it is because you changed with old age. In the end Tommy Lee's character can't keep up, it's why he retires. I thought one of the parts of the movie was when tommy lee was talking to the fat guy about how violent the people were who commited the murder of the guy who stole the money. That is when the movie really clicked with me.
If you didn't like the ending, it makes me really question why you ranked No Country so high, because the ending is such an important part of the themes and ideas presented in the film.
As far as conflict resolution goes in the movie, what is not to like? The killer is not caught, still punishing people according to his personal values. The Wife, I assumed dies, protecting her own personal values as well. And most importantly, Tommy Lee retires going to more simple things that he can keep up with.
