True to its name, the demon, Ratsasan is a psychological crime thriller which manages to keep the audience on their toes from start to finish with its intense story line and commendable performances especially of Vishnu Vishal. The film truly deserves praise for its brilliant direction ( by Ramkumar) and immense research which does serve aspects of drama which is both necessary and at times overly done. Catering well to human emotions, the movie even manages to discuss efficiently strong social issues. Though the romance between the protagonist (Vishnu Vishal) and female lead (Amala Paul) seems to be done just for the sake of attracting audience, the movie as a whole is very well created. Props to the crew , the cinematographer (P. V. Sankar) and special effects team for their contributions as well.

All in all, this is a highly recommended watch!
