I can never forget the first time i saw this film n i couldn't believe this was a malayalam film, never even knew Kamal Hasan had acted in such a film...No doubt he must have liked the story, it's engaging from scene one... This is no doubt one of the finest malayalam vendetta thriller films, if not one of the best indian thriller films imo....everything is top notch especially the technical side, from using the gadgets for revenge n the ideas behind each scheme...It was equal to watching a Hollywood thriller film...No loud dialogues, no larger than life superheroes, it's all a brain game like chess...I read the lead role was meant for mammootty, no doubt he would've done a fine job but the fact remains this role was meant for Kamal Hasan...U don't expect a lean short man to become so cunning, intelligent n dangerous, and he breathes life into this character, even the bgm is so apt... All movie lovers irrespective of language who likes to watch malayalam films must not miss this classic revenge thriller...The interesting fact is It still can be remade into present time... A film ahead of it's time in Indian film... Tragedy that director Rajeev Kumar couldn't make a brilliant film as this one in his future career...This remains one of his of his most finest works.
