Tze Chun’s luminous indie American feature debuted at this year’s Sundance Festival, where the kids-on-their-own story attracted international attention. The film focuses on a brash Chinese single mom in transition between jobs, housing and hope; her two children somehow manage to hang on when she doesnt’ return from her Ponzi-scheme conference. Blending kids-eye lyricism with a remarkably unsentimental realism, Children Of Invention offers some extraordinary performances, particularly from the two young stars at the centre of the this gripping but ultimately uplifting narrative.
