I finally saw it tonight. Goddamn. Alec Baldwin wrote on the Huffington Post that it was a metaphor for Iraq, but I totally disagree. You could make a case for Chigurh (pictured above) as a metaphor for ghostly terrorists who lurk everywhere waiting to kill slack-jawed Americans, but I don't know. I'll be thinking about this movie for weeks.
All I know is that it was brilliant, jarring and intensely suspenseful. If you've ever had a nightmare in which you're being chased and no matter where you hide, the monster or villain in your nightmare somehow finds you... this movie will make you squirm. In a good way.
Anyway, I'm reading Cormac McCarthy's Blood Meridian right now, but as soon as I'm done, I'm reading McCarthy's original No Country For Old Men.
