First part of No Country

I felt that the title No Country For Old Men kinda was influenced by the idea that the Sheriff is the old wise figure in the story, one of the oldest yet throughout the chase and investigation he is always one step behind. He says a couple times that he feels like these new criminals are ones they can't control, that it is beyond the control of anyone in general because they are too ruthless and sharp to be caught. Chigurh is really one of the best villains ever because he is so methodical yet is willing to kill someone like that clerk just for getting the wrong vibe from someone. He makes you feel like anyone could be thinking about killing even in a convenient public place like the gas station where normally you feel safe, whereas at home something like that is much more likely.
