We gain more understanding,and deeper appreciation of the story ... Let's read Hollywood Reporter's Review.....
1997. Yong-gu (Ryu Seung-ryong) is a mildly handicapped parking garage attendant raising his daughter Ye-sung (Gal So-won) on his own, though she’s clearly the keeper of the household despite being six years old. Yong-gu wants to get her a Sailor Moon knapsack, which leads him to follow another child down a quiet Seoul street to a shop that has them in stock. The second girl -- the police commissioner’s daughter -- winds up dead and Yong-gu is quickly judged kidnapper, rapist and murderer. Yong-gu is fingered as a child-killer in the big house (never good) but after saving his cellmate, Boss Yang-ho (Oh Dal-su) from a shiv in the yard and other displays of pure goodness, the remaining cellmates soon come to understand Yong-gu’s been railroaded. During Yong-gu’s incarceration, Yang-ho and his crew -- academic Chun-ho (Park Won-sang), wily lifer old man Seo (Kim Ki-cheon), secretly sensitive thug Bong-shik (Jung Man-shik), flamboyant Man-beom (Kim Jung-tae) -- conspire to smuggle the one thing Yong-gu wants into the prison: his daughter. Cue hijinks.
The prison escapades with Ye-sung form the bulk of the film, a rambling comedy that’s every bit as absurd as it sounds. But silly as it is, director Lee and his team of regular writers commit fully to the fantasy and build the world so completely it’s easy to let reality slip away. Even the primary set, the prison cell, exists on a fantastical plane. Production designer Lee Hu-kyoung’s bright, homey jail is free of steel bars and bare concrete (the toilet has a door), shot with soft edges by cinematographer Kang Seung-gii to be a space fit for a little girl; it certainly looks nicer than the classroom Ye-sung attends at the orphanage. And it is the prison sequences that contain the most genuine laughs, often refreshingly non-reliant on toilet humor. Ye-sung’s decision to color over the Playboy pinups decorating the walls, Boss Yang-ho’s reading lessons and the sight gags built around keeping Ye-sung hidden are among the highlights.
