Malini Mannath of Chennai Online wrote that "It's still a fascinating experience watching this actor [Karthik] in action, his endearing natural ease and spontaneity. But the fire in him is missing and the disinterest shows on the screen". A critic from The Hindu wrote, "Initially Naveen Muthuraman (the story, screenplay, dialogue and direction are his) gives the impression that patriotic fervour will dominate the proceedings. But soon it turns out to be just another story of bad and good men, their guessable ploys and boring [cliches]".
