For me, its rating should be 9/10.
Every scene was precisely shooted with the most appropriate emotions, expression and the most important thing, Story plot was great. Best combination of thriller, emotions and moral. Actually, I loved the role played by late Srideviji and Nawazuddin Siddiqui. Although my review is unbiased and I really never expected such a good movie from Bollywood. But still, I want to say that after watching this, I missed her a lot. May her soul Rest in Peace.
