The movie is brilliantly made with several twists to it, mostly unpredictable. Asif Ali's acting bandwidth was stretched to the maximum when it reaches the second climax. The setting is mysterious. The movie felt more like a horror thriller than a mystery or an investigative thriller.
The background audio elements at times was a little overboard and overshadowing the plot. Read about a few loopholes in a discussion forum. Otherwise, a good watch.
