There was a huge hype created when Surya was about to be casted in the movie.And indeed the hype was paid off. Everyone who compared this with Taare Zameen Par ,I won't say that your absolutely wrong. But few scene did remind us about that movie. Maybe the reason because the kids deal with the similar kind of disease or because a mentor character like Amir Khan was required in this movie which Surya has played. The kids have done an excellent job. They have probably understood each and every dialogue given to them. Cause these scenes have come out indeed really well. And surya has also done a neat job. Even though the dialogs given to him make us feel that Surya is the only person on earth to understand kids. But anyways his role adds some audiences to this movie. Because that is what is required for this movie. It teaches many who don't know parenting . Like how a parent should start by nurturing a kid from the day the mother is pregnant. This was indeed something new. On the whole the movie was a neat one to tamil cinema. It would have become a boring documentary or the message told in this movie would not have reached wider audiences if Surya would have not acted in this movie
