The surge of South Korean cinema onto the global stage has become an undeniable cultural phenomenon, a wave that crests higher with each new offering from the land of morning calm.

While the world may have been first ensnared by the meticulous class warfare of Parasite or the shocking, dystopian tension of Squid Game, it is the thriller genre that proves to be the true, beating heart of this cinematic export.

Netflix, with its voracious appetite for cutting-edge international fare, recently delivered another potent dose of this dark artistry with the swift, stylish brutality of Mantis, a film that has once again solidified the Korean knack for crafting narratives as sharp and unforgiving as a scalpel’s edge.
