A definite must-see! Reminiscent of Bigelow's "Zero Dark Thirty" and Soderbergh's "Traffic". Great cast (kudos to Del Toro, Blunt, and Brolin), solid story and execution, visually engaging. A refreshing take on the gang/drug problem in the US-Mexico border, and how one's search for justice and order figure in the whole picture. Not your typical action movie (don't expect "loud" action sequences), but definitely the scenes that matter (and there are lots!) are compelling and memorable. Hands down one of the year's best!
