Shankar's Gentleman and Indian has created a separate fan following for the vigilante-type action films in which Saravana Subbiah's Citizen is also added. This vigilante action film speaks loud about a strong social issue. It follows the same path as Shankar's vigilante films. The originality in this film is the way that Saravana Subbiah has treated the screenplay. Citizen is a very much different Ajith film. It features him in dual roles where he has to sport 9 different getups for one role which created a big buzz for the film. Saravana Subbiah has built a perfect action film in which there is much more importance for the content than the entertainment factor. More than the content, the film works brilliantly for Ajith. He is the one man who lifts the film with his dedicated performance. He fits well in the two roles and shows his versatility with his performance. We can easily call this film one of his best performances. The flashback sequence is a major pillar of the film. It is a well-made sequence and a must-watch for the presentation. After Ajith's performance, Citizen shines for its content only. Saravana Subbiah made sure to stick around the idea for the whole film but unfortunately, he fails on several occasions. The comedy sequence featuring Vasundhara Das is a huge letdown because it feels misplaced in the film and we don't need it in such a serious film. It actually ruins the overall seriousness that we had for the film. Another major letdown in this venture is the pace. Citizen is approximately a 3 hours film. Honestly, it would have been much grippier if we cut down the unnecessary scenes in the first half. The logic factor hits really hard in Citizen. We have some logical mistakes that bring down the quality of the film. The CGI is really poor. It seems rushed a bit and could have been made much better. Saravana Subbiah has made a strong film that shows his ability to pull off a unique and interesting idea within the conventional commercial template. Overall, Citizen is an interesting vigilante film.
