Mother (2009)

An absolutely phenomenal film by the Korean director Bong Joon-ho.

Its combination of dazzling cinematic craft, psychological insight and black humor make this one of the year's moviegoing musts -- and even or especially at her most deranged, Kim Hye-ja's amazing mother is profoundly, passionately human.

Again as with Bong's earlier films, Mother is a genre exercise that honors convention, yet weaves around it whenever possible. Bong carefully turns Mother into a classic gumshoe tale, with red herrings, interrogations, and moments of sublime suspense.

A superb murder mystery, with twists coming thick and fast yet always at the right moments.

The hard-pounding heart of Mother, Ms. Kim is a wonderment. Perched on the knife edge between tragedy and comedy, her delivery gives the narrative -- which tends to drift, sometimes beguilingly, sometimes less so -- much of its momentum.
