Debutant director Paranthaman's Ragavan, starring newcomers Vijith and Radhika Malhotra in the lead, is a good example of how a movie that is not well-made! From beginning to end, the film drags with an array of feeble flashbacks, amateur performances and inappropriate songs, with no sign of tempo. Produced by Selvaraj under the banner Ankitha Productions, Ragavan was planned as a psycho-crime-romantic thriller, but unfortunately disappoints all sets of audiences in all aspects.

What is its storyline? Set in the backdrop of a different post-modern call centre culture in which sex and luxury are part of stress management, Ragavan is the tale of a village boy Ragavan (Vijith), who comes to Chennai to complete an IT course. When he was a child, Ragavan happened to witness his father (Moonar Ramesh) murdering his mother and her paramour; the same scene comes to him repeatedly in his nightmares. From then onwards, Ragavan has a psychological disorder to kill those who lead immoral sexual lives.

Unfortunately, due to his conservative nature, Ragavan has to face a lot of mental stress in Chennai. Initially, he stays in his aunt's house, but escapes from there after being sexually abused by her. He loses his certificates and is forced to take up small and menial jobs for his livelihood. Working as an auto rickshaw driver in the night and as a tea supplier in the day, he stays near the house of Divya (Radhika Malhotra), a model who falls in love with him.

While plying his auto rickshaw at night, Ragavan comes across many amoral persons from the IT industry indulging in extra-marital sex  and kills them all. Rumours spread that a psycho killer is behind the murders. Assistant Commissioner of Police Lakshmipathi (Manoj K. Jayan) takes charge of the investigation and manages to trace and arrest Ragavan. Lakshmipathi comes to know about Ragavan's painful past and the story ends with the court acquitting Ragavan on the basis of his psychological disorder.

Though the story seems to have commercial values, it is a total mess on screen! The director apparently has no idea about where to start the story and how to proceed further. As a result, the film lacks a flow in its narration right from the beginning. Since the director seems too much worried about what to show next, he has even forgotten to establish his characters' identities. For instance, the director has failed to make any impact on the audience in presenting his lead character as a psycho killer. The film does not have even a single scene to show how intense his psychic disorder is! However, he must be appreciated for daringly depicting some of the crucial moral problems faced by IT professionals.

The biggest letdown in the acting front is that Vijith and Radhika Malhotra do not share any onscreen chemistry. Vijith looks physically weak, while Radhika Malhotra is a Namitha look-alike.  (In fact, Radhika is a close relative of Namitha and has been directly recommended to tinsel town by Namitha.)  Due to this, the romance between Vijith and Radhika is often a matter of fun for the audience. Radhika's dialogue delivery makes it evident that she is non-Tamil. Though Vijith and Radhika deserve applause as newcomers, they must improve their acting skills. Moonar Ramesh as Ragavan's father and Manoj K. Jayan as the Assistant Commissioner have done justice to their respective roles. There is nothing to talk about the technical aspects. In short, Ragavan fails to impress!
