Two sisters on Mexican vacation are trapped in a shark observation cage at the bottom of the ocean, with oxygen running low and great whites circling nearby, they have less than an hour of air left to figure out how to get to the surface.
47 Meters Down is a serviceable survival thriller with a genuinely tense premise — two women trapped in a shark cage on the ocean floor. The cinematography captures claustrophobic underwater dread reasonably well, with murky lighting and disorienting depth adding atmosphere. The concept is distinctive enough within the shark-horror subgenre to earn modest novelty points, as the cage-sinking angle separates it from typical shark-attack fare. However, the plot is thin and relies heavily on contrivance to manufacture tension, the acting from the leads is functional but unremarkable, and the ending — while attempting a twist — feels cheap and somewhat unsatisfying rather than cleverly earned. Overall a middling genre entry that delivers some scares but lacks the craft to elevate it beyond its B-movie roots.
