Karthi's Saguni, billed as a political-satire, sets an example for an ordinary story born out of weakest screenplay. What was expected to be as the edge-of-the-seat entertainer has merely turned out to be a loosely-made film with no logics whatsoever! The only silver line of the Tamil film is Santhanam's comedy.
The film begins with the death of CM played by Chandramohan, a political conspiracy hatched by Bhupati (Prakash Raj) played by Prakash Raj, thereby setting the tone of the film on a serious note. But it takes the next 40 precious minutes for the director to get into the main story. In the first half an hour, we are introduced to Kamala Kannan, who beats around the bush to tell his past towards auto driver Apparao Durai alias Rajini (Santhanam), who assume that the former is rich and spending or driving him through the city is profitable for him.
