People would say this movie is more of a realistic one but the thing is that there is a bit of poetic expression in many scenes that breaks many stereotypes and are enjoyable. Dhanush rules the screen such that inspite of his body language, the viewer will accept him as a gangster once the script gets the pace. Unlike other gangster flicks where the lead will come up from the slums and all that drug trafficking stuff, this one gets into political world that too in a realistic manner.
Technically of a higher class where the cinematography and the use of colour palattes and lights help much in expressing the multiple moods of the film. Music is just out of the world with multiple grooves and much experimental tunes that hit the right chord well.
With a world class script and a director like selva, this is a timeless masterpiece that would inspire young filmmakers. One problem is with the excessive bloodshed that would not be appropriate for family audiences. Except for that this is one of those movies a cinebuff will long to see again and again
