There is no doubt that Vidya Balan is a great actress and no one can deny her capabilities to perform any character.
But what she can do if the script of the film itself is so poor that you lost you interest in the film even before the interval.
Bobby is an struggling detective in a conservative family living in old city of Hyderabad. Its her story to prove that women is capable of anything in mens world and to show her old boss and family that she is more than a normal girl.
The thought around the film was good but the plot to explore Bobbys journey was total useless and does not generate any interest at all.
Over all can be seen just once and only for Vidya.
