The TVI Take
Bong Joon-ho's 2009 thriller anchored by Kim Hye-ja as a small-town mother investigating her intellectually-disabled son's murder accusation. The structural commitment to letting maternal-protective cognition be the actual subject — and to refusing the conventional resolution most thrillers in this register would provide — is the film's distinctive achievement.
Among Korean cinema's most carefully-constructed character studies.
