The invaders hadn’t expected her to be ex-military, able to eliminate a threat quickly and effectively. It looks like a routine home invasion until Erin fights back. The dinner that follows is tense and full of fighting. Crispin’s family is old money and are not on good terms. The setup is ordinary and relatable: Erin accompanies Crispin, her boyfriend, to a family reunion up in the outskirts of Missouri. It looked like just another home invasion film, right down to the outwardly annoying cast of characters (which ironically makes it all the more satisfying to see them get killed) however, what it did so well involved how they displaced who had control between the victims and invaders.
