In my view the movie was good but was very predictable. The reason behind the predictability was the trailer. The trailer revealed a lot about the movie. Apart from that acting was to the point. The background noise was a bit louder. It was not a very horror or nail biting movie. Parental guide required only for kids. I just felt Madhavan could have been little more scary in his looks. And yes Ajay was similar to Drishyam, saving his family. But he was better in Drishyam. Overall good movie to watch one time.
