Oldboy by Park Chan-wook is deffinitely not for everybody, but those that choose this film will find it rewarding in the most depressingly way. Extremely stylized from the opening scene, this korean tragedy will take you on a rollercoaster ride you will not soon forget. There are some discomforting scenes of violence and sex (... just watch the movie), but all with good purpose to the development of the films message. If you have the stomach and mental calluses to watch this film, you will not be disappointed.
