A top class film. Period. Even if you ignore the sad incident and all the anger that will eventually manifest inside you as you watch events unfold in the movie, this is, without a doubt, one of the best Indian movies in recent years.
Ranganathan Madhavan is a madman who will stop at nothing to put his heart, soul, blood, sweat and tears into a project he believes in. His direction is really, REALLY good and Nambi Sir's story has been told beautifully by Mads here.
Please watch this. This is cinematic heritage.
