Chander Uday Singh of India Today wrote, "Although Bhatt has used artistes with little cinematic experience (barring Hattangady and Phule) he draws superb performances from them. Kher stops short of being brilliant only because he occasionally lapses into a vigour out of keeping with the ageing and broken Pradhan. Hattangady, fresh from the success of Gandhi, remains convincing in the difficult role of Parvati." In a retrospective review on films 30th anniversary in 2014, Sukanya Verma of Rediff.com wrote, "Bhatt's finest film, which celebrates its 30th anniversary on May 25, isn't comfort cinema.
