Thinking a bit more about my last post on the mini-series, Chernobyl, and on body horror and systemic horror, and their relation to one another: body horror is somewhat about losing control of your physicality, your body (in this case, radiation destroying your body), while systemic horror is somewhat about losing control of how you can act, and behave, and be (in this case, managers and state officials dictating dangerous behaviour — along with consequences for not carrying out said behaviour).
Chernobyl combines them: for instance, managers forcing people into situations that lead to radiation poisoning and the harm of their bodies.
