The pilot episodes failed to effectively draw me into the characters & hindered my emotional investment in their journeys. This weak start sets the stage for subsequent disappointments. However, I was able to finish the drama because of my love for Han So-hee.

Notable, was the lack of nuance in Park Seo-jun's portrayal of Tae-sang. Despite the character's complexity, Seo-jun's performance falls short, making it challenging to connect with Tae-sang's internal conflicts about self serving motives and altruism. His comedic moments lacked freshness and the clever wit needed to bring more depth to his character.

The forced and unconvincing romantic plotline between the leads is totally unnecessary & almost childish.

So-hee's acting prowess is evident but is hindered by shortcomings in the script, making her character's journey less compelling.

Lastly, the quality of dialogue was notably subpar & lacked the richness it needed, coupled with the majority of scenes taking place at Onseong Hospital being repetitive and boring, which diminished the overall viewing experience, especially given the historical context of the drama.

Overall, the multiple plot lines could've been better integrated to make the drama seem more cohesive.

I'm skeptical but I hope part 2 of season 1 will renew my interest for season 2.

Edit: I finished all 10 episodes & I'll stick by my initial rating. Now that I have finished the drama, I think I can confidently say the casting for this drama was absolutely OFF. I felt like a lot of people were miscast and that is why this drama does not deliver what it should've - I did not find myself at the edge of the seat, the creature was not scary tbh, the villains were boring and nothing stood out per se. It is what it is.
