I have to admit to being a huge Cohen brothers fan, so that may have biassed my opinion, but this was hands down my favorite film of 2007. Tommy Lee Jones and Javier Bardem are remarkable in supporting roles and Josh Brolin continues his breakout year in the lead role as Llewellyn Moss, a Viet Nam Vet who stumbles on the aftermath of a major drug deal gone bad. The film is Cohen's first adaption of existing material. It is, in fact, an extremely faithful adaption of Cormac McCarthy's 2005 Novel of the same name.
No Country starts quickly introducing Javier Bardem early as Anton Chigurh(pronounced SHIGURR)a sociopath whose presence in this film can be compared to that of Hannibal Lecter in Silence of the Lambs or the shark in Jaws. He becomes the antagonist to virtually every other major character in the film. The pace is steady and unrelenting easing off only at the very end as the Cohens wrap things up in a manner that while atypical of Hollywood and even of the cohens is however perfectly faithful to the novel.
Jones and the Cohen Brothers deliver, Bardem is Badass and even Woody Harrelson is less "Woody". See it.
