After four years of Kahaani, director Sujoy ghosh makes Kahaani 2 a watchable movie, but it fails to keep a tight grip on its duration. Unlike Kahaani, Kahaani 2 lacks a bit. Sujoy ghosh is partly successful in narrating a thriller movie with the audience sitting at the edge of their seats till first half but fails after interval because of loop holes which makes movie predictable in end . Kahaani 2’s ending is predictable and dumb.Now on acting .Vidya Balan proves that she can caary any movie on her shoulders with her acting skills .Arjun Rampal did a decent job in a cop role .The Soundtrack of this film has been composed by Clinton Cerejo, written by Amitabh Bhattacharya .songs like mehram and labhon ke rasgulle did not fits in the movie .Cinematography is commendable throughout the movie.at the end Kahaani 2 is a one time watch movie.
