The title meaning Parattai alias Azhagu Sundaram, itself projects the dual nature of the hero. Azhagu Sundaram enacted by Danush is a young village lad who is the only son of his parents. His mother dotes on him. Azhagu's father dies of some disease and he moves to Chennai in search of a job. Events lead Azhagu Sundaram to be re-christened as Parrattai and is forced to wield the knife. From an innocent youth from a rural area, he goes on to become a gangster. As ever, he is the don with the heart of gold, who commands respect from people around him. Unknowing this Parattai's mother comes in search of her son to the city.
 
Dhanush as Azhagu Sundaram and Parrattai is compelling and full of conviction. His sincerity stands out, especially in the weak script. His character has shades of the lead role enacted by him in Pudhupettai. Giving him good company is Meera Jasmine. The Meera magic charms the screen too.
 
However stealing the entire show is former National award winning actress Archana, playing Dhanush's mother. She has given great emotions making the movie magic work. Anger, love, affection, desperation and dejection, are all portrayed well by her. Santhanam as Dhanush's friend does evoke laughter. Unfortunately the weak link of this film is its storyline. It is an often-repeated and beaten up track of Tamil cinema.
