He has not made it very preachy. Rather Sampath Arumugham has woven a crisp screenplay and ensures that events that occur are close to reality. Ramana's patient wait seems to have paid off. The actor has had many medicore outings and was looking for the right break. His patience and perseverance seems to have been rewarded with Mahaan Kanakku. He has utilised the opportunity well to deliver his best performance.

Seemingly inspired by news reports on families being affected by the alleged atoricities of some private banks, the director has gone ahead with the movie that seems to serve a purpose.

Jeeva (Ramana) is a happy-go-lucky youngster. He leads a contended life in Coimbatore with his sister Janaki (Devadarshini) and her husband Vardharajan (Srinath). For Jeeva's higher education,  Varadharajan obtains loand from OCOC Bank. Though he repays the loan, for no reason he is harassed by bank officials and collection agents. He is humiliated by them at his workplace and his residence too. Unable to bear their tortures, Varadharajan commits suicide with his family. Only after their death, Jeeva comes to know about the incident.

He now vows to teach these private banks a lesson. Jeeva comes to Chennai on a mission now.

He fakes his identity and uses all loopholes in the legal systems and borrows huge money from banks. One fine day without repaying them, he disappears. How the bank officials run behind him. Eventually he is caught and brought to a special court where he throws light on the atoricities of these banks and gives a call that private banks be nationalised for they have spelt doom for many families.

Ramana does a wonderful job. He is good and refreshing. He plays a mass hero and shoulders the responsibility well. Reecha Sinha who plays the heroine appears briefly. Sreenath and Devadarshini give a matured performance while Saravana Subbaiah delivers the goods.

Slick editing by Suresh Urs is another major highlight. All events unfold at a quick pace. A couple of songs by Rishi Sai are nice to listen to.

Three cheers to the filmmaker for handling a bold theme and sets off a debate that is more relevant for contemporary society.
