Not a great "Rohit Shetty" type stuff. But yes atleast a one time watch and that too not on a theater. Kajol was looking great and acted as casual as she is in real life.
Varuns part was quite funny in between. Shah Rukh looked same and no variation in his acting part.
Songs were good to listen, specially "Gerua", which give a very unrealistic feel. Though as an entertainment source and art, I liked the view the director tried to show to the viewers and that too which looked great on big screen.
Overall a 6 / 10.
