While the 1st half of the film is pretty powerful, the 2nd one is pretty confusing. Soo-jung Ye is fantastic in the role of Hyo-jeong, a self-confident old woman, who claims that a young male nurse has raped her. "An Old Lady" wisely takes the matter of rape accusation based reliability to the edge, but instead of being a police-crime drama it gently becomes a personal film that takes care of the victim's feelings and her struggle with bureaucracy.
But all this is true about the 1st half, while the 2nd one is pretty strange. After one of the characters goes through an off-screen accident, new side characters and conflicts suddenly appear and take most of the attention from the main one. Despite enriching Hyo-jeong's and Nam Dong-in's (Hyo-jeong's boss and friend) world, it has really little to do with the main story and mostly felt pretty flat.
