The soundtrack was composed by Thaman S. "Aathadi Aathadi" received a high response from audience.
Malathi Rangarajan of The Hindu wrote, "Suspicion, murder and the aftermath form the fulcrum. At a superficial level, it is a chilling story of sibling rivalry, but the suspense, when it is unravelled, has some surprises in store". Sify wrote, "On the whole, Ayyanar is a mass film that is found wanting in tempo and packaging".
