The story started strong and the torture part or the way a predator thinks was protrayed well. However it's a misconception that only apparently poor people like a Toilet Cleaner can be torturous, many privileged people do that behind closed doors, even mental abuse, no one knows about it. In the end they showed the mother also committed murder. Sometimes cinema's protrayal of crimes instigate more crimes in society specially among the youth. More or less a good story. Must watch
