I love the vibes of the 60s era. I have to say they did a great job. I like that each episode represents different case and I love the way they solved the cases. I like that it is inspired by Korean history and how difficult it actually was to catch bad guys.

I am amazed by the first half of the drama as it has really funny moments and the dream team was build. To be honest for the the second half was loosing its charm. Also it is upsetting to see that no one cares about normal people except the unit 1 and the corruption is on different level. I guess nowadays it is the same but they cover it much better.

The drama is easy to follow as the cases are not that difficult to follow so it does not need your full attention.
