A crime thriller and a series of murders in city is a theme that is touched rarely by our filmmakers. Commercial cliches are order of the day and films are made in a pattern with songs, fights and romance these days.
But debutant filmmaker Gnanasekar has opted a least treaded path in Nan Sivanagiren. The movie seems to have borrowed the concept heavily from films like Kadhal Kondein, Nadunisi Naaigal and the evergreen classic Sigappu Rojakkal.
A totalof 14 married women gets murdered in Chennai. He settles down in a mansion with his friends. He comes across one Prabha (Varsha) and falls in love with her. Slowly they get close to each other when Varsha gets the shock of her life. She comes to know that Prabhu is behind the killings. As events unfold, Prabha lands in cop's nest and it is revealed in detal why he turns serial -killer. he has had a bad past and its the reason for his act.
Karthik and Varsha play their part well. Karthik with his serious expressions fits the role well. Varsha portarys innocence and oozes with energy.
However the movie has shades of many earlier films that includes Kadhal Kondien and Sigappu Rojakkal. A decent attempt indeed.
