It's hard to review this without giving the story away too much. It is a story about love and relationships: not just romantic relationships but between parents and children. It has its light romantic side in among that.
However it also has deeper messages for Indian traditionalists. I gather that traditionally many Indian women do not remarry when they are widowed but are condemned to live a perpetual bereavment with their in-laws.
The movie challenges traditional values and looks to a higher wisdom and greater heart as relevant principles when this happens. So it is also a compassionate movie. It is also about putting ones own ego aside for the sake of others happiness and coming from love instead.
Amitabh Bachchan plays a man of great wisdom, heart and integrity and anchors the movie. It is a moving performance. The other actors similarly do a solid job. A lot is asked of Rani Mukerjee and she rises to it with a breadth of acting and response.
Her 2 love interests to some extent are secondary to the main story but both do well and whether you like them may depend to a large extent on whether you are generally fans.
With my foray into Bollywood it's the first time I've seen John Abraham as other than a muscle bound 'hunk' (not my usual taste in males anyway!) This time he plays a gentler romantic hero and, while that took a bit of adjusting to, he did it well.
I see from other reviewers that Salmon Khan brings a mixed response in people. In this movie I thought he was fine and did what was required.
This movie is about wisdom, integrity and heart and it left me moved. To me that's a very desirable mix.
While it's called a drama and has very dark, serious pictures on the cover it isn't a bleak movie and does have a lot of lightness in it but it does have themes of grief as well.
