Oldboy breaks into a classic three-act saga, the first of which details the hallucinatory period of imprisonment in which Oh Dae-Su wades from mild insanity to outright psychosis in the hands of unseen yet attentive captors. Act 2 is the revenge, when an entirely different tone takes over and Oh Dae-Su moves with single-minded purpose and clarity. It's this section that has gained the most notoriety, primarily for the claw-hammer dentistry scene, the one-man-army tracking shot, and the wriggling octopus that Oh Dae-Su consumes in a sushi bar (he's been dead so long he simply needs life back inside him in any way possible). In act 3, answers finally start to emerge and the sinister atmosphere grows even more profound--not without a healthy dose of extra bloodletting, of course. Oldboy is an undeniably poetic masterpiece of tension, fury, and dynamic craft. Ultimately, its epic cycle of tragedy is of the sort that mankind has been inflicting upon itself for all time. Some of the images may be gruesome, but all converge into a kind of beauty. It's in the telling of this lurid tale that these details become one and the memories of pain ultimately heal. --Ted Fry
