So, the question is how the actors visualised and played their character.
By that yardstick, Ajith who is far superior to Rajnikant in his acting prowess has done a miracle. Repeating a movie that came in 1979 in a different language in 1980 is no miracle.
But making the same story run in 2007 is, and Ajith has done it. Hats off to him!!!
