The use of symmetry is used a lot in this movie. It relates to the idea that the concept of doubles is viewed as creepy within human-kind because there is something disturbing about the idea that there can be duplicates of something, or that one thing can be two conflicting entities at once. The “evil-twins” concept is used with the shining as they are introduced with no context to the audience, but simply give off a creepy vibe by the way they are stood still, staring at Danny. The way they hold hands means that there is no good twin, evil twin. If they are evil entities, it means they are both evil since they are shown to be on the same page as each other. This creates a frightening feeling for the audience because we don’t know what is going to happen next, and the “double” idea is generally creepy. As for specifically the twins, there is something for-boding and corpse-like about their demeanor. Their sunken-in eyes stare at Danny and there is something very unnatural about their symmetry, they are not identical but they don’t need to be. It’s the idea that if one of them is terrifying enough. Two of them up the horror ante.
