IFFBoston continues at the Brattle tonight with The Handmaiden.Set in the 1930s this intense, stylized film tells the of a Korean pickpocket who is drawn towards an Japanese heiress she is meant to defraud. But there are wheels within wheels, as the complicated plot unfolds in three acts. Complications arise not just from individuals scheming, but also Japanese colonialism, patriarchy and class divisions. But it’s set pieces of lust (and brief moments of grotesque violence) that stand out. At the Brattle this evening.
