It's a basic story taken from a small but crucial page of history. It doesn't matter if it's historically accurate or not. I watch for entertainment, not for class. I got Mr Sunshine vibes with an upbeat western feel. I remember the main character from "Live up to your Name" a good Joseon Era to modern day time travel series. It was cool to see scenes blending old and new times. The weapons ranged from swords, shotguns, and bows and arrows. There is a possibility for a second season given the short number of episodes. Despite its small flaws, I enjoyed the story and the characters.
