Great movie, the only thing I never really liked was the end, I do not know the reason.
What happens to Brolin's character left me very confused, and then something very sudden happens to Chigurh as well. I do not know, maybe one day I will see it with different eyes and the end will finally end up liking me, but for now, the only thing I question about the film is that.
Another thing that I like about this movie, are the dialogues, the coin scene is just great, it transmits a lot with little.
And I agree with you, Chigurh is one of the best villains in history.
