warmed-over cold war cliches
The central weakness of Citizen X is its overuse of warmed-over Cold War cliches. The first part of the film, which takes place during the Soviet period, focuses on the inefficiency, rampant cronyism, and general ineptitude of law enforcement under the Soviet system. Once the Soviet Union falls, Russian law enforcement is miraculously transformed; the old bureacrats are sent away and the Citizen X investigation becomes a model of efficacy and professionalism. There are at least two problems with this proposition:
1) Russian law enforcement is, if anything, even less efficent and more corrput under the current system than it was in the late Soviet period.
2) Cronyism, corruption, and incompetance are widespread in law enforcement agencies throughout. These problems were no more (or less) prevelent in the e Soviet Union than in Mexico, Pakistan, Gutemala, or any number of other countries. US law enforcement is no exception; my home state (Illinois) put so many innocent men on death row that former (Republican!) governor Goerge Ryan issued a moritorium on capital punishment.
It is clear Citizen X was to supposed to "expose" the sorry state of criminal justice under the Soviet system. While, the Soviet justice system was indeed sorry, it was no more so than elsewhere. In the end, what the film shows is how much salience knee-jerk, anticommunist cliches still have in the US today.
