The ones directed by Zoya Akhtar and Karan Johar was quite spine chilling and created an aura of suspense and thrill.Infact in Zoya’s movie the mom kept calling for his ruthless indifferent son even after death she was waiting for her only child to come back was very clearly indicating towards our social degeneration.Its realistic as old people are left alone in their last stages and society is a mere spectator .However the other two directions by Anurag Kashyap and Dibakar Banerjee created aversion more than fear and thrill ,was obnoxiously unrealistic .Jahnvi Kapoor was excellent her acting prowess will take her a long way
