well i started this with 0 expectations, even tho i waited for it for so long, i just finished after staying up all night.
so let's talk about it
Plot?
the drama is not only about missing people, you can see they did a really good job expressing how some people Really suffered in the 1940's when south korea was under Japan's control, this made it even better, the whole hospital thing is just amazing and i never expected it, it fits the plot perfectly, Japan using poor korean citizens and stuffing them in a hospital try on experiments, turn them into Monsters to use them in war? its pretty smart to be honest.

Acting/cast?
Perfect cast, park seo joon, han so hee and wi ha joon are the perfect combination for a 1940's drama, and since they're amazing actors, the acting was really good. amazing actors, fluent in japanese.

the drama was pretty unique, unlike any other drama about monsters or zombies, gives 1940's vibes, war vibes, colonisation vibes, soldier vibes, also it was emotionally in the right place with some good plot twists , a solid 10 for me, can't wait for part 2
