Eddie Cockrell of Variety praises 'Pandora's Box' as a confident and satisfying drama that skillfully delves into character development and pacing. He highlights Tsilla Chelton's remarkable performance as the Alzheimer's-afflicted matriarch and commends the production designers for authentically capturing the contrast between urban and rural settings, tradition and modernity. Cockrell notes that the film's exploration of the clash between old and new offers captivating insights into a country undergoing transition.
However, Joanne Laurier, reporting for World Socialist Website from the Toronto International Film Festival, notes that while the inner and outer worlds of the characters are well dramatized, the film's critique of urban isolation seems to yearn for a simpler era. She raises the question of whether this nostalgic longing for the past is genuinely helpful in addressing the complexities of contemporary society.
