Vetri Maaran is moving from strength to strength in directing Polladhavan and Aadukalam. Both Dhanush starrers, Aadukalam used rooster fights akin to human psyche. We are envious of our own kin, we plot against our own flesh and blood and when reality strikes we deny it. Vetri Maaran is a firm believer in taut screenplays and there is never a dull moment.
