One of the best crime thriller in Tamil. Definitely will become one of the best in this genre.Vishnu in the lead role have reprised his role convincingly and with ease.All the supporting actors have put up a very decent show.The Plot has got a lot of twist and turns which keeps you engaged all the time and as the movie reaches climax you will be at edge of the seat.BGM plays a very crucial role and hence theater experience is must to enjoy this movie to the core.Long running time is one of the negative aspect for this thrill but considering the storyline and development of characters this long time is required.Also there are few twists which makes you feel like whether it is required or not.But as said before when you are on the roller coaster ride all these things won't affect you and In the end you walks out of the theater with satisfaction that you have watched one of the best movies this year.!!! Kudos to the team of Ratsasan.!!!
