Very good film with an unexpected twist. The plot goes from comedy drama to thriller drama unexpectetly in the last minutes. Film depicts class differences, struggle and greed for money in South Korea society but truly no different than any other part of the world (it could be US or Europe). The viewer is taken for a wild ride of feelings ranging from empathy to disgust about the behavior of the characters, then again viwers are forced to evaluate morals and the fine line between right and wrong. All together this is a story about surviving social class difference as faith of being humans.
