The movie, being a sequel to directors fresh and delightful Pyaar Ke Side Effects, starts on a high note. The jokes are good and you have some really smart dialogs and funny situations as the first half progresses. Especially the part where Farhan tries to feel like a pregnant lady. However that's where the good things end.
Second half is a Mish-Mash of emotions and multiple characters which are totally wasted. Taking nothing away from Farhan or Vidya's acting, it's the director's confusion about what he wants to show that is the culprit. The love a father may have for his child has been totally ignored with Farhan's character treating his daughter as nothing more than a hassle as there is no father-child connect in the movie. Characters like Vidya's mother and Vir Das are underutilized. Even Ila Arun's character has been mis-handled.
The movie tries to show the issues a couple with kid with single income may face, yet we never see Farhan working hard while whining about expenses all the time (While living in a luxury house by Mumbai standards). The movie completely loses its plot and the climax leaves a bad taste as a half baked attempt.
I would still say it deserves a one time watch for the first half which comes as a tasty appetizer, its the main course that got burnt.
