At its basic essence, this show resembles a lot of MCU movies. You've got a hero origin story, a mystery surrounding hero and cast, and a enjoyable cast of characters who play off each other. But it is still a kdrama and like other kdramas, it can't really stick the landing.

The first half of the series is great and builds upon itself really well. It introduces the world extremely well and gives us some really good moments. The villain of the week format is universal and serves as a good introduction into this world. But after the half-way point, the story pivots to focus on the final villain. From there, each episode varies and has issues. Some episodes feel like they are speeding through story and moments, other times it feels like the show is creating scenarios to just extend the story a bit more. There are plot holes and the rules of the universe change randomly without good reason. It becomes a bit unfocused and because of that, I don't think it deserves a 9/10.

Even knowing the writer switch, the problems existed with the old writer as well. If there were really discussions about shortening the length of the drama, the writer didn't do anything great in the later episodes that totally showed that the drama should have ended a few episodes earlier. I know there will be a second season but I am worried about what happens in the future. Some characters were sidelined and poorly used in the last couple episodes. On top of that, there were questions posed and dropped. The comedy-drama balance was a bit off as well. I do hope that the new writer could start over in a way and find a new way to tell the story that still can maintain the same quality as before.
