Sujoy Ghosh failed to achieve the level of thriller of first one however it was worth watching Cine Maa for Vidya Balan and Arjun Rampal. Sujoy Ghosh successfully delivered Child Abuse issue with great message like we have seen glimpse in Highway movie from Alia Bhat. Script need little more surprise elements in second half as this one was totally predictable one. Supporting roles of Jugal Hansraj , Manini Chadha and cute Tunisha Sharma were good. Music is another weak point as you will badly miss Ekla Chalo Re type song from Big B.
If Kahaani was the mother of all stories then Kahaani 2 is the child of Kahaani
