Tribeny Rai’s debut feature, Shape of Momo, has one of the most indelible heroines of any Indian film in a while. Bishnu (a bristling, unforgettable Gaumaya Gurung) returns home to Sikkim to superimpose her Delhi-imbibed expectations on a familiar place and people she thinks she can amend. But a rude awakening awaits her. Bishnu is prickly, wary and intensely reactionary, not eager to wrap herself in docility or submission which she judges both her sister, Junu (Shyama Shree Sherpa), and her mother (Pashupati Rai), as having compromised and living too cautiously. The fierce, unapologetic Bishnu refuses to soften or brook. You expect Shape of Momo to move in a certain direction until Rai, along with her co-writer, Kislay, daringly complicate the heroine’s centrality of assumption. The question of class intrudes and suddenly a linear, neat avowal of privilege and easy feminism interrupts.
