It would be tempting to describe the Oscar-winning documentary Taxi to the Dark Side as "devastating" if it weren't for the dispassionate approach Alex Gibney takes to the material. That's not to say the film lacks passion, but merely that emotional manipulation is not among Gibney's goals. The director of Enron: The Smartest Guys in the Room has assembled an extensively researched, sober, and straightforward presentation of the facts related to the Abu Ghraib prisoner abuse scandals, and others that occurred under the watch of American troops in the Middle East and Guantanamo Bay. His film also reveals the success of the PR campaign designed to blame the smallest cogs in the machine, designed to dismiss them as "bad apples." The malevolent glee in some soldiers' eyes, made famous by the notorious Abu Ghraib photos, may inspire outrage. But Gibney's interviews make it clear that these men and women were indoctrinated into a multi-faceted program for extracting information from enemy combatants. To question it would have run contrary to everything they were taught about following orders, but this rationalization didn't save them from prison sentences, public disgrace, and private disillusionment. Taxi to the Dark Side provides numerous opportunities to ball one's fists at the policies and attitudes of the Bush administration, which seem to have directly resulted in spawning new terrorists. But again, Gibney lets the facts speak for themselves, rather than engaging in a Michael Moore-style hatchet job. With Enron and now Taxi to the Dark Side, Gibney has emerged as one of the most prominent investigators of systemic corruption among documentary filmmakers. If his film is not as shocking as it might have once been, that's a statement on modern media saturation and our collective loss of innocence, rather than on the stark dehumanization explored here.
