"Beneath" is a Horror film grounded in the claustrophobic and psychological subgenres, combining elements of survival thriller and true-event drama. Typical horror elements it includes are a confined, isolated setting—in this case, a coal mine deep underground—creating intense feelings of entrapment and vulnerability. The atmosphere grows increasingly oppressive as toxic air and limited resources escalate the tension. Additionally, the narrative explores human psychological deterioration, with the characters' descent into madness and paranoia causing internal conflict and turning them against one another. What makes "Beneath" stand out in the horror genre is its basis on true events, which adds a layer of realism and emotional weight, enhancing the terror by grounding it in plausible human experiences rather than supernatural phenomena.
