I highly recommend to watch this movie for two type of audiences- first, those who expect a good thriller from Indian cinema (of course not only Bollywood) and second, those who have only heard Kamal Hassan's name but never watched his any single movie yet. Kamal parts here dual role, one as an old man (Senapathy) who stops the corrupted people, and the other as his son (Chandru) who works in transport department concerning licenses. Kamal did brilliant job in this movie by offering both the roles of a father and a son. Perhaps, if examined clearly this is his career reflecting movie. There are some high definition visual scenes where we can see the real freedom fighters like Subash Chandra Bose and Senapathy together. This is a remarkable work from director Shankar, or say in Indian cinema. His directorial works are highly appreciable. For action lovers also this movie is a good reference.
In romantic words, this is a love-triangle movie due to the presence of Manisha Koirala and Urmila Matondkar, both who love the same Chandru. They did their own works, and run the movie. But again, this movie falls under three categories- thriller, political (mixed with social) and patriotic as the title itself denotes. I watched countless times, but never felt bored as it is highly entertaining for the three hours continuously. It has two versions, original one in Tamil and another in dubbed Hindi version. In Hindi version there is a slight uneasiness with the uttering words of the actors in their lips as those do not match exactly, since it is a dubbed version.
