Intrusion gives a wicked kick after an intense roller coaster. The film's use of the initially portrayed victim's point of view makes viewers feel fearful of what uninvited thing has come into their house. The film  does this well with heavy breathing and rapid movements of the camera. After a brief and intense confrontation, the viewer will suddenly realize that he isn't the victim at all. This becomes the "wicked kick" as the viewer will realize that he/she has been the villain all along.
