Rating: 9/10 (5 October 2013)

"Oldboy" is a mind-bending revenge tale that ventures into the emotional extremes, and no chance of emerging exhausted unscathed. Full of grand passions, bloodthirsty violence, with a wicked sense of jet black humor, "Oldboy" is a sadistic masterpiece. The director, Chan-wook Park, is one among several filmmakers who've made South Korean cinema what it is today, and requires a viewing at least once by serious moviegoers.
The plot is utterly unique: Seoul businessman Dae-su Oh (Min-sik Choi), is kidnapped one rainy evening by parties unknown. He awakens in a seedy motel room – complete with hideously tacky wallpaper, threadbare carpet, a double bed, and a television – but in reality, it serves as a cell. Days, months, and years go by with no explanation given for his incarceration. A daily meal comes through a tiny slot in the door, and every so often sleeping gas seeps in as well. From the television in his room, he learns that he is the prime suspect for the murder of his wife –- and now, even if he escapes, he's a wanted man.
Fifteen years later, Dae-su awakes one day on a grass-covered roof of a downtown building in Seoul, outfitted with a finely tailored suit, a cell phone, and a wallet stuffed with cash. Before Dae-su can begin a new life, he must answer several key questions about his imprisonment. Only after he has these answers can he exact his revenge and turn the page. Meanwhile, his captor decides to turn Dae-su's quest for answers into a cruel, exhausting game that will push him to his limits. Additionally, he has just five days to not to only find out why he was held captive, but to also identify his tormentor, and seek his revenge.
The committed performance by Min-sik Choi strikes a genuinely tragic note amid the mayhem and cartoonish excesses of violence. He does a marvelous job walking on the edge of insanity, while retaining likability and compassion from the audience. Superlative acting across the board, and a pulsating score to compliment the arresting imagery, while the true astuteness of the script will reward only on further viewings.
"Oldboy" has a wild, twisty storyline on such an epic scale emotionally, and it rarely slows down to consider the logic of some of its most outrageous plot contortions. The revelation in the third act is a bit of a letdown considering the thrilling, ambitious set up. Cinematic in the extreme, the movie has an emotional core that will leave some viewers stunned, yet others disgusted. As tough as it is to endure -- it is brutal, yet brilliant -- and it is undoubtedly a work of art.
"Oldboy" is the second installment of The Vengeance Trilogy, directed by Chan-wook Park, preceded by "Sympathy for Mr. Vengeance" (2002) and followed by "Lady Vengeance" (2005).
