No Country for Old Men

The Coen brothers have managed to create an oppressive and captivating atmosphere, where the tension grows with each scene. Javier Bardem's impeccable performance leaves an indelible mark, conveying an almost palpable danger in every gesture and word. However, the distant tone and the narrative structure, which stays extremely faithful to its literary source, may feel somewhat cold to certain viewers.
spoiler:
The direction is masterly, with absolute control over image and rhythm, but the story seems to resist offering a conventional or emotionally rounded conclusion. Do you think that ambiguous, almost nihilistic ending adds more depth or leaves a feeling of emptiness?
