The film is said to be an anthology, where all the stories or segments happens within 12 hours. Director Meera Kathiravan has attempted to show what happens in Chennai post midnight, with all the necessary elements expected in a movie such as; love, action, suspense, thrill, friendship, etc. He has done a good job in the directorial department, but has failed to keep the audience hooked to the film as the screenplay is draggy and unorganised, which makes the viewers question where the story is going on?
Through all the drawbacks, the film may have been unique and fresh if it had hit the screens right after it's post-production in 2012. Because compared to debut director Lokesh Kanagaraj's fast moving and interesting Maanagaram's story, which is similar to Vizhithiru, the latter's story is a bit deviating and clumsy.
All the main cast Krishna, Vidhaarth, Dhanishka and Venkat Prabhu has pulled off their respective characters really well, while debutant Rahul Bhaskaran has delivered a notable performance. SPB Charan, Thambi Ramiyah, Baby Sara and Erica Fernandes have done justice in playing their parts neatly. Vijay Milton and RV Saran's cinematography skills come to fore and they have shot well. While Sathyan Mahalingam has composed the music, and his scores justify the movie's genre.
In short, Vizhithiru, is interesting.
