Though the director Susi Ganesan had given notable films like 'Five Star' and 'Thiruttu Payale', he became the talk of the town only when he started a mega project, 'Kanthasamy' with the national award winner actor Vikram. It is termed as one of the costliest films produced in tamil (produced by Kalaippuli S Dhanu). The pre release reports and promotion works of the film were gigantic. It made the project very big and created more expectation. The news regarding the different getup and appearances of Vikram and the shooting in Mexico all created the extra hype needed for the project. But the main challenge here is that any negative reaction for the output will affect such a big project too badly.The hero, Kanthasamy (Vikram) is a CBI officer. He seizes the unaccountable money from the rich and distribute it to the poor. Like the website in 'Annyan', here the people writes their wish in a paper and hangs in a tree near the temple. In the night the hero takes a different appearance to destroy the evil. The director's way of showing the super heroism (with the help of hero's friends), felt amateur. Villain (Ashish Vidyarathi) and his daughter (Shreya) makes a plan and thus she gets closer to the hero since the former is being raided and a case is filed against him for doing illegal business. Since the director has not created any suspense in the hero's character, the power who attacks the villains is found out easily. The reason told by the hero for this is borrowed as it is from 'Annyan' amd 'Shivaji'. Anyway in the end, love matters becomes serious and the villains are destroyed accompanied by a lengthy speech by the hero. You have got comedy scenes by Vadivelu, as the side track, which is also below average only.Susi Ganesan, who had also acted in the role of a CBI officer here.
