This is my first review in IMDb and the first movie itself is a top notch one for my review ! Vishnu vishal as a cop masters the role and gives his career best performance and this will be his career best role !! Munishkanth Ramadoss should get special mention for his emotional role . Amala Paul , nizhalgal Ravi , Suzanne and others gave enough amount of life to their character ! BGM is the one which elevates this plot driven psycho thriller with high points and seat edge thrilling experiences in it's whole run ! Cannot reveal much about the plot ,the villain and the reasons behind the murders . Go watch it in theatres for a spine chilling experience and yes .. it's a MUST WATCH and a breakthrough for thriller genres in Indian film industry !
