It's a great movie bt I think it's an adaptation of a bengali story "KONI" beacuse full story is same bt the director changed the sport. In the story it's swimming bt here it's boxing. Bt other things are same.....like the girl came from a slum area , she is a sport lover , the coach was a good coach bt now he is suspended , and all......bt RAJU HIRANI wrote the script very well so it's a nice film
