Indiaglitz wrote "Director Thirumalai deserves credit for coming up with a movie that is fairly engaging."^[3] Sify wrote "There is nothing new in story or presentation and the film sags towards the climax, and is a total let down. Thirumalai, the director has etched the plot of the film from Dharani?s action movie Dhil, added some masala, and remixed it".^[4] Chennai Online wrote "The script hops, skips and jumps through situations without much consistency. So, by the time you get tuned to one situation, the director has gone on to a totally new one. And by the time you get acquainted with this new one, you are distracted by a different track. The messages are varied, conveyed in a confused way that doesn't make any impact".^[5]
