47 Meters Down is a horror thriller that embodies key elements typical of survival horror within an underwater setting. It features isolation, a ticking clock with limited oxygen, and an antagonistic natural predator—in this case, great white sharks—creating an intense atmosphere of fear and suspense. The confined setting of a shark observation cage deep underwater amplifies the claustrophobia and vulnerability often found in the genre. What makes it stand out from other horror titles is its unique combination of deep-sea survival with shark attack themes, merging psychological tension with visceral creature horror, all while maintaining a relentless pace and escalating danger as the sisters struggle to escape before their air runs out.
