There have been many Tamil movies that have had superb story lines. However, three such movies stand out for the superb performances. These are not movies starring the legend called Sivaji Ganesan. The scintillating actor that he was, he was also known for his pronounced over acting. Still, his movies like Pasa Malar, Deiva Magan, and Baabu will figure within the best ten.
My choice of the three is: Uthiripookkal ( the fallen flowers), Naayagan, and the recently released "Kaakka Muttai"
