Cruelly underrated because of its release with other films like 96. Generally mystery thrillers won't be true to its genre in Tamil cinema. But this one does and a lot more. No compromise on the story with long drawn romance or planting useless songs here and there. Plot can't be thicker and the twists and storyline will keep you in the edge of your seats. BGM is terrific. And the acting and direction is too good. 2nd Half is filled with creepy moments and may unsettle you a lot. A must watch if you need pure entertainment for two and half hours.
On the whole, a brilliant mystery thriller laced with scary sequences. Go for it.
