The continuing tragedy of Hindi cinema is that it is in the grip of the hegemony of a few stars, who patronise a select few filmmakers, often resulting in the tripe that is offered to the public. I was told by two of these megastars that Hazaaron Khwahishein was one of the worst scripts they had ever read. What these stars did with their next films is a part of history that I don't wish to dwell on.
