Must Watch List! "Oldboy"

9. Oldboy – Park Chan-Wook’s twisted revenge fantasy boasts one of the most pathologically compelling protagonists in film history. When Dae-Su wakes up imprisoned in a ratbag hotel, he's unaware that he has just embarked on a journey that will break his down to the very core of his being. Unfortunately, what's there is a guy who really likes to destroy people and eat live octopus.
