Gritty social study? Or borderline exploitation? First-time Serbian director Maja Milos arms 16-year-old Jasna (Isidora Simijonovic) with a mobile phone, then intersperses this slice-of-life, Belgrade-set drama with staged footage covering everything from posing and carousing with her girlfriends to the explicit nitty-gritty of her sexual ‘relationship’ with her boorish boyfriend. Meanwhile, at home, dad is dying, money’s tight and Jasna deals with it by partying harder. Clearly there’s a state-of-the-nation intent here, revealing a toxic cycle of machismo and female submission, but it’s never compelling enough to outweigh misgivings at the prurient visuals, notwithstanding the on-screen declaration that 14-year-old Simijonovic did not participate in the sex acts depicted.
