Was pleasantly surprised by this one. Expecting a competently executed but forgettable trendy-gloomy action film, I instead got an unusually abstract, operatic immersion into spiritual hell that sees the various corrupt parties of the drug war dissolve together into ceaseless, futile carnage. A dread-ridden, political-minded psychological thriller simultaneously worthy of Kathryn Bigelow, Michael Mann, Clint Eastwood and Johnnie To.
