Two-time Sundance Film Festival award winner “Sonita” tells the inspiring story of Sonita Alizadeh, an 18-year-old Afghan refugee in Iran, who thinks of Michael Jackson and Rihanna as her spiritual parents and dreams of becoming a big-name rapper. For the time being, her only fans are the other teenage girls in a Tehran shelter. And her family has a very different future planned for her: As a bride, she's worth $9,000. Iranian director Rokhsareh Ghaem Maghami (“Going up the Stairs”) poignantly shifts from observer to participant, raising legitimate questions about documentary ethics but offering Sonita undeniably essential aid. An intimate portrait of creativity and womanhood, “Sonita” highlights the rarely seen intricacies and shifting contrasts of Iranian society.
