It became quite apparent right off from episode 2 that this was a massive flop. The drama would have worked wonderfully and masterfully as a movie or at least as a 3-4 episodes short drama, otherwise, it's absolutely riddled with problems in its current condition and format. The unique setting and scenery weren't enough to help its case. It ingeniously transformed the art of storytelling into a chaotic, avant-garde mishmash of disjointed scenes that left me pondering the deep mysteries of life, such as whether the writers had ever heard of structured narrative or if they were just operating under the belief that plotlines are mere suggestions for lesser beings. Each plot twist, if one could even call them that, was a tantalizing leap into the abyss of narrative incoherence, leaving me on the edge of my seat not in anticipation, but in a desperate attempt to maintain my balance amidst the swirling vortex of plot holes and character motivations more elusive than a unicorn at a camouflage convention. I can't thank the creators enough for their valiant efforts to reduce character development to a cryptic crossword puzzle that nobody asked for, but we apparently all deserved, according to them. I wish to see better attempts going for a similar setting and theme from more competent creators. It's hard to recommend this drama unless you're a diehard fan of some of the cast members. Jun Ji Hyun disappearing for ~5 years then coming back with this project was nothing but a disappointment. It made it harder to be excited for her next project "Polaris (2023)".
