Sridevi plays Devki, a biology school teacher, wife to businessman husband Anand (Adnan Siddiqui), stepmom to Anand's rebellious teenage daughter Arya (Sajal Ali), mother to a younger daughter. Arya is resentful of her stepmom. Meanwhile, Arya's porn-sharing, drug-snorting classmate Mohit (Adarsh Gaurav), disturbed by her rejection, resorts to extreme measures, leading to the film's revenge premise.
Neither a compelling drama nor a wise social comment or a heart-stopping thriller, Mom is solely salvaged by its performances.
Sridevi rules her scenes, Sajal Ali is very effective as the rape victim, Nawazuddin Siddiqui as a balding small-time detective almost steals the show with much-needed humor and impeccable timing. The very deserving Akshaye Khanna is saddled with a dim, one-dimensional role, so is the menacing Abhimanyu Singh. Both needed backstories for their contrasting actions.
Mom rides on Sridevi's amazing, enigmatic talent but fails to hold its own. The standout scenes that gave me a shudder - a black SUV going down an empty road to AR Rahman's apt background score. These are the only moments when the film stands apart from the formulaic skeletons of similar Hindi films. Finally, Mom is just a tad above disappointing.
