Reception
Malathi Rangarajan of The Hindu wrote that "Taking up a story that touches upon ESP, effluents, pollution and the havoc it creates on human life, Ramesh Krishnan places them in a genre that spells horror. The result is quite interesting. Those of you who like to experience just a bit of fear, the occult kind, can make a beeline for Adhu".[2] A critic from Indiaglitz wrote that "Spirit is there. But the other spirit is slightly missing".[3] Malini Mannath of Chennai Online wrote that "It's Sneha's film the whole way. But making an impact is debutante Suha as Kalaivizhi, and new face Arvind who projects creditably the cynic who later goes all to support Meera".[4]Sify wrote "But the trouble with Adhu is that it does not provide you with the chills and thrills associated with a ghost story. Though the film is only 116 minutes it drags and the special effects are too cheesy and amateurish. The climax looks like an amman film, as the spirit and the evil tantric clash".[5]
