A killer has it's reasons but the opportunists who make a buck over a crisis are equally vile and it seemed to be the takeaway of this story. While the society is sheepish and ignorant the killers lurk and this hunting grounds of stranglers is made to picture carefully gloomy cold colour tones adds the misery of death to visuals. Excellent performances by the cast in depicting the maze that's traversed to get to the truth. Great use of audio keeping up with the tension of the chain of events. Great writing that gives characters unique traits through dialogues. A movie that's well made in all aspects.
