What critics said
Critics broadly found it an engrossing, well-acted science-fiction thriller with effective horror elements, while noting that its restraint and shifting genre emphases limit its impact.
What sets it apart
May contain story progression spoilers
The crew must isolate and monitor one another as the parasite spreads through their water supply.
The marine organism threatens the trawler while the film connects outbreak anxiety to environmental disruption.
The trawler's narrow corridors, dark compartments, and sealed water systems make the vessel feel increasingly inescapable.
The film gradually escalates parasite and sea-monster dread through psychological tension rather than constant attacks.
