This is great storytelling from start to finish. The first episode is a full on rush introduction to the incredible Demon Seo and there will be more of that action along the way with the context supplying a wealth of real life material. It delivered far far more than I expected from the trailer and IMDb info. Loved the intertwining of the past and present stories/personal histories of the characters. A rare role for a very strong female leading character--this by itself s a huge plus . Excellent chemistry between Demon Seo and her Newbie partner. The "supernatural" element was unexpected, intriguing and added a creative layer to the script. If simple and light this is not. It's a series which demands attentive engagement. Love the entire cast. Wish there was another season. Totally binge worthy!
