I saw it with my son the movie kid, and we both loved it and want to see it again, but we have a weird disagreement:

ok, don't read this if you haven't seen it!
When the sheriff goes back *alone* to the motel crime scene, and actually enters the room, don't we see Chigurh hiding in a closet? So he's actually got the lethal killing machine bad guy cornered! ...but then he lets him go...?!? If I have that right, then that's a major moment: the sheriff either knows or suspects that Chigurh is still there (came back after everyone left, to find the money stuffed in whatever air vent) but he also knows that he's outmatched, that trying to capture this particular bad guy, he can't do it, he'd die and Chigurh would get away anyway.... MAJOR realization, for him and us - the good guy can't always win...
