Post New Korean Cinema emerged in the mid-1990s and emphasized imaginative genres over realism. There were three main types: Park Chan-wook's provocative violence and negative imagination seen in Sympathy for Mr. Vengeance, Oldboy, and Sympathy for Lady Vengeance; Hong Sang-soo's experimental films that exposed the hypocrisy of daily life like Day a Pig Fell into the Well; and Jang Joon-hwan's uniquely expressed films such as Save the Green Planet that used confusing visuals beyond normality and were critically successful despite box office failures.
