A shy old woman—shy enough and old enough that her fine, flowery outfits have become integral to her sense of self—discovers that her callow grandson has participated in an awful crime and only she can protect him from prosecution. The premise of this South Korean import may call to mind that of another, Bong Joon-ho’s recent suspense film Mother (2009), but Poetry is another bird entirely: true to the title, writer-director Lee Chang-dong (Oasis, Secret Sunshine) is principally concerned with rendering emotions that seem inexpressible. Before the scandal begins to unfold, the woman joins a poetry class at a local community center, though modesty inhibits her from writing her own verse; like many beginners, she’s frightened by the idea of reaching within herself, yet her inherent grace and dignity are the very qualities poets prize. In Korean with subtitles.
