Even though many says that it is based on a real story, I dont think so. Many says Rajinikanth is playing the character of a mafia Don from Chennai named "Kabaleeswaran". It is just for popularity, just a normal fiction film.
After the movie we feel little disappointing as its not upto the expectation or upto the teaser. It is a normal gangster film. First half is good but remaining average.
I think stories about its based on real life is just for popularity.
