It’s rare for horror movies to use robotic villains as their antagonists, but there are a rare few that manage to make killer automatons seem downright terrifying. Compared to horror movies starring ghosts, traditional human slashers, demons or other monsters, killer robot films seem to be at a disadvantage. It can be hard to find a way to make a sleek-looking automaton seem threatening, and the human-made nature of robotics makes them more “knowable” and practical threats to overcome.
