I bet this would be one the all time best psycho thrillers in Tamil cinema. Hats off to the entire cast and crew. Especially to Ghibran. His BGM was the real Ratchasan. It added more thrill to the storyline. Sitting in a movie for 175mins without getting boredom is a very rare sight these days. This masterpiece made that possible. This movie should be part of the all time greatest Indian psycho thrillers. My only disappointment was they wasted some 15mins overall showing Amala paul Vishnu vishal romance. Actually it wasn't that romantic anyways. That part could have been filled by more thrilling clips. But still I would give 10/10. Purely for the way the storyline was scripted and the BGM.
