Wow...! I expect this level of expression from Bollywood. In the midst of nonsense and illogical movies, comes a piece of powerful and sentimental love,emotion and drama. It is based on a Father - Daughter relationship which people may call weird but, in fact it is depiction of situations of all old and sick parents in the world, specially India. Why should u watch it ? Because Bachchan Sir has given us a memorable and subjective touch through his acting as Piku's father. It shows how a daughter never forgets her duties even when his father irritates her by impulsive and relentless behavior. It shows how a man accepts death happily. It shows love is not a treaty. It takes us to a life changing journey from Delhi to Calcutta by road ! Just exchange of thoughts and love sprouts from strangest of places with strangest of people no matter what are the circumstances. Irfan is as expected, Deepika fits to the role, Amitabh sir is unforgettable.
