People need to understand that every movie is not about entertainment. Actually movie is a medium through which your thoughts and emotions gets conveyed and this movie does it brilliantly. His 'true' mother is not interested talking with him and although he knew she is his mother he didn't call her 'aai' for once. No family drama about why his 'true' mother is not taking care. At the end when he calls 'aai' to one who is taking care of him. There was reference in the film, the scene where in his class some student was explaining why Sant Dnyaneshwar is called as 'mauli- the one who take care...'. Nothing in this film is dramatic, just pure emotion. Whole movie is an emotional ride, through first half gives quite bit of nostalgic feeling(to those who can relate) and second half is all about understanding the meaning of 'aai'.
