So to begin with the script typical cliched cat and mouse chase. But when it comes to the screen it just explodes and leave thriller buffs awestruck. The plot points are the ones to watch out for, people who have been reading movie scripts for a long time/ reading Wikipedia plots of movie will be very astonished at the way the plot points are being placed. It's a thriller movie with some horror elements. What's acres is not the appearance of the killer instead it's the BGM and his modus operandi. The actors have done their jobs perfectly. Especially the protagonist 's brother in law and the titular killer.
