Auro (Amitabh) is a 12 year progeria infected kid living with his gynecologist mother Vidya (Vidya Balan) and her mother (Arundhati Naag). Exceptionally sharp Auro happens to win an award in his school from a young politician, Amol Arte (Abhishek).

On the same night when Vidya watches its telecast, she realizes that Auro actually met his father for the first time. During her student days abroad, she was in a relationship with Amol but had broken off with him over their decision whether to keep the child or not.

Amol wanted it aborted and not commit for marriage as he wanted to pursue his political goals. Progeria affected children don't happen to live beyond 13-14 years so when Auro collapses and she fears he is nearing his final stages of his life, she discloses to him that Amol is his father.

What follows next and how Auro is influential and getting his separated parents back together forms the rest of the movie.

Paa is R. Balki's next after the greatly lovable Cheeni Kum (2007). Balki had showcased glimpse of his brand of cynical humor in his debut movie and with Paa he has completely established it. The movie has been cleverly narrated cutting away from unnecessary melodrama. The pacing is just perfect. The selection of child actors (including Mr. Bachchan) deserves special mention. They act their natural self and are extremely very funny. Paa has plenty of magnificently written and enacted sequences like Auro's conversations with his best buddy in school Vishnu, Auro's sequences with his stuffed toy King Kong, Amol – Vidya's argument over whether to keep their child or not, Amol exposing his critics on live national television, Auro and Amol's chilling out all day in Delhi, Amol realizing Auro is his own child and finally of course the climax.

With his Auro act, Amitabh Bachchan yet again proves he is the Paa of all his generations where acting is concerned. The natural manner, in which he has carried out such a challenging act, deserves a long standing applause. He is definitely bound to win all the acting awards for this one.

Abhishek Bachchan has put up a very full-grown act. In fact you may want to hate his character in the movie initially, but full credit to him for making it very likeable. Vidya with her body language succeeds in communicating her single mom mayhem. She is effortless natural as well and looks wow. Arundhati Naag is very good. Paresh Rawal in a short role as Abhishek's father is well controlled.

The movie scores very high in the technical department. Music maestro Ilaiyaaraja's music is tuneful and flawlessly interwoven with the movie. His background scrore is fresh. Anil Naidu's editing and PC Sreeram's cinematography are superior.

Watch Paa with your parents and one can confidently say that it is absolutely bound to be an experience which you will remember for a long time.

Paa will leave you with a tear in your eyes but also a smile on your face.
