This is a really good time-travel mini-show. The storyline is interesting and exciting since there are a lot of twists and turns.
Character wise:
FL is a strong and independent woman with really good investigation skills.
ML is a simple but strong general who doesn’t know much about life outside the army. He has great perception skills.
Acting wise this is pretty good and the actors do a good job within the limited timeframe.
So, if you like a good time-travel show - with a major twist in the end - this is well worth watching.
