Ambitious but lacks legibility and not as convincing as they promised.
The movie starts good but the investigation spun 360degree when they introduced the Killer. Some of the scenes are kind of inspired but its okay as far as it serves the story good, But in this case, They didn't.
Like I said, It was an ambitious attempt which kind of failed to grasp the authenticity of the story somewhere close to the end. It felt so silly and uninspiring.
