Alright, I have such such mixed feelings about this drama. I'll split it into pros and cons. Pros: Seon Jae: I honestly love SJ a little too much. He is pretty much the main reason why I was watching the show lol. Anyway, why did I love his character? A. I found him somewhat relatable. He is someone who doesn't trust easily, needs a reason to open up to somebody, but once he's made a friend he's made a friend for life. B. I just love his story of how devoted he is to his mother and his mother's case. C. He's just so adorable ok! I just love how he really cares about the people around him, but doesn't like to let onto it too much, it cracks me up. D. He's just an all around good guy. He's hardworking, loyal, devoted, and the list could go on. Kwang Ho: I really like how they made his character true to the 80s. He thinks like a guy from the 80s, which means he's a bit sexist and a chauvinist. I liked seeing the contrast of how he thought of things compared to present day. And sometimes the past was better, but sometimes they were so wrong. The show did a really good job of portraying that through his character. I also just loved his character in general. He's handsome, loyal, hardworking, courageous, and honest. Bromance: Alright, this was also one of the main reasons why I was watching the show. I just loved the bromance between Seon Jae and Kwang Ho! How it went from hating, to tolerating, and finally to genuinely caring. It just bloomed in this real lovely way and I absolutely loved it! I haven't seen a bromance as good as this one in a really long time. I just really loved it. Acting: Acting was on point in this drama. Wow Seon Jae, Kwang Ho, and even Jae Yi really brought their characters to life. I could feel their emotions, it wasn't acting it was living. Feminism: Oh wow, there's some great feminist under-tones in this drama, and it's fantastic! When Jae Yi asks the police "did these women deserve to die?" I was like you go girl! Yeon Sook and Kwang Ho romance: They had such amazing chemistry, and I just really loved how much they cared for each other. Yeon Sook was such an amazing woman, who has admirable faith in her husband. Though not the focus, they were definitely a beautiful couple. And I wish that I can have a marriage like that one day. Emotion: This drama's true strong suit is emotion. It packs in the emotion well. A lot of crime dramas, it's simply about catching the criminal. But with this drama you really see how the killings affect people's lives. We're not just catching criminals, we're saving lives. I truly felt the emotion attached to the victims and the victims families. As much as I love Seon Jae and his story, he is not the only reason why I think this. The side cases had a lot of emotional impact too (I nearly cried during one, I never cry lol). While Seon Jae's mother's case was the highlight case, each case was important. The women that died, were people, with lives and families. And you felt for each and every one of them. Not every drama can do that, so I applaud this drama for not only caring about suspense, but reminding viewers that these are people we are talking about. And in real life, when cases like this happen, it is a person that died. Someone with family and friends, and nobody deserves that death. Episodes 1-9 plus episodes 11 and 16: These episodes are really the strong point of this drama. There's good pacing, smart characters, humor, and touching moments in these episodes. Episodes 8 and 16 were truly amazing, and I applaud the writing and acting. They were truly memorable episodes. Cons: Most of these cons came out during episodes 10-15 (save 11). So really only 4 episodes, but it was enough to bother me and really frustrate me. I would say the last half of the show wasn't as enjoyable, and was downright frustrating at times. Plot: I like to know what the plot is. I like mysteries, but not the actual plot to be a mystery. For example, God's Gift is one of the best mysteries I've ever seen. But the plot is very clear, to save main girl's daughter. This drama I wasn't sure what the plot was till the very end. Was it to go back in time? Was it to catch the criminal (future)? Was it to catch the criminal (past)? Was it both? Was it all 4? I really had no idea, and this made the drama very frustrating to watch, especially the last half. Jae Yi: I just didn't care for her character. I didn't hate her, but I didn't love her. And if we're being real, I just didn't like the fact that she interfered so much with the bromance towards the end. I'm cruel like that though. If I have neutral feelings or disliking feelings towards a female character, and she starts to interrupt the bromance, I will start to get annoyed with her character. Even if she didn't really do anything wrong. I also found her a bit creepy in the beginning, and there's something she did I found a bit hard to get over. I don't know for the most part she was very meh for me. I mean she had some touching moments, but still. I just didn't grab onto her. Stupid Characters: Ok, they weren't always stupid, they definitely had their smart moments. But sometimes the writers would decide to make their characters stupid to prolong the suspense. Like sorry, I don't like suspense for suspense, I get really annoyed if suspense is being created because a character is being dumb. Ending: I loved the last episode I really did! Episode 16 and 8 are by far the best in the series! But, for real there should've been another episode. Overall, would I recommend this drama? Sure, go ahead. It's good, and the ending episode makes it worth it. Would I call it a masterpiece or a classic? Lol no. It's good, but there are too many plot holes and facepalm moments for it to be a masterpiece. The plot was a bit too all over the place for my taste and the things that made the show amazing at first got toned down a bit in the last half (save the last episode and episode 11). But it's still a good drama and overall there's more good than bad.
