Post-college identity grappling gets a political twist in Amu. Kaju (Konkona Sen Sharma), a recent UCLA grad staying with relatives in Delhi to reclaim roots, learns that her parents did not die in a malaria epidemic as she had been told. Instead, they perished in the anti-Sikh riots, set off when Prime Minister Indira Gandhi was assassinated by her Sikh bodyguards. Soon her self-absorbed search for authenticity expands to a deeper quest for truth. Too bad first-time writer-director Shonali Bose’s juxtaposition of the personal and the political often feels forced, and like many didactic history lessons, this one’s about 20 minutes too long.
