Set in contemporary Mumbai Sir is a sharply crafted romantic melodrama, full of warmth, about a benign architect, Ashwin (Vivek Gomber) and a migrant servant, Ratna (Tillotama Shome). The script is sharply written and brings to life the complexities of Ratna and Ashwin who are are bound by class and caste. Although they are two people from opposite ends of the social spectrum, the emotional connection that is forged becomes a tentative bond and gradually emerges as a painful longing that reaches a memorable conclusion. The narrative unfolds from the perspective of Ratna and for much of the film remains with her character, which is significant because a romantic melodrama of this type could easily have capitulated to a male point of view. The script is wonderfully underplayed and Tillotama Shome in superb form brings to life the nuances of Ratna, a widow who works in the city to support her family back home and has aspirations of becoming a tailor. Writer and director Rohena Gera treats Sir as an urban fairytale and thankfully channels much of the emotional interplay through subtle gestures and precise framing. If marketed with vigour and picked up internationally Sir has the potential to crossover and reach the critical and commercial heights of a recent Hindie breakout like The Lunchbox.
