This show is phenomenal! It is a must-watch for its innovative storytelling and intense emotional journey, provided you're prepared for its stark portrayal of death, suicide, and related disturbing content.

The story is gripping and a contender to dethrone Netflix's The Glory as the reigning psychological K-thriller, if Amazon Prime markets this enough. The work probes into dark but fundamental themes related to the struggle to survive. It explores mortality, love, family, and regret. It exemplifies the narrative depth and scale characteristic of leading K-dramas, filled with moments for laughter, sobbing, and introspection.

The production features an ensemble cast, although not quite at the level of this year's Moving. Writing is tight. Cinematography is beautiful and meticulous. VFX might not match top Hollywood quality, but there are masterfully choreographed set pieces that keep you on the edge of your seat. For fans of the genre and newcomers alike, this is a series that demands attention.
