There has been mixed review with this drama and I could totally understand, however- despite what people may say, this drama is definitely worth a watch! Story It started off spectacularly! The thriller and suspense/mystery were done so well that it had me hooked right from the start! It starts off with a mystery right off the bat which was great since it didn't drag on from the start. However- nearing the middle and end; that is where it slightly goes downhill. I felt like the drama was dragging on despite only 10 episodes. The reason being is because I felt like they were using fillers instead of developing the main story. What I mean from that is that I wanted to see more murders being solved with the help of Na Yeong (the ghost), however it felt like the filler episodes contained more of her possessing Ha Sun Woo just to get out of the police station and experience a care-free life such as shopping or drinking soju. That was the cons of this drama; as it didn't really mention or further went into depth with other plot devices- as I wanted to learn more about Cheo Yong's blood ability, about his past, or how he even managed to possess or find the special knife. I found that there were several plot holes that didn't explain some of the things in the drama very well. Despite the problems that I found in this drama; I truly thought that this drama was interesting and the concept was great! This drama really deserves a watch even though the reviews might put you off! Plus it's only 10 episodes so it's not an entirely waste of time! Actors/Cast There were no problems with their acting! I didn't like some of their characters such as Sun Woo's character since I found her to be kind of useless at times. Na Yeong the ghost seemed even more helpful than the actual cop herself. Speaking about Na Yeong, Jeon Hyo Seong did a fantastic job portraying a dead high schooler that wanted to experience different things in life. Her bubbly personality was cute and I really liked the fact that she was useful at times. Oh Ji Ho who portrayed Detective Yoon Cheo Yong was fantastic as well! Really like his portrayal of character even though I find him irritating at times with his mentality of 'I can do everything by myself' Despite that; i really think everyone did a great job! Music Oh man- I really liked the instrumentals in this drama! I am a huge fan of instrumental soundtracks that give off an epic/ suspense filled vibe! I will definitely download some of the tracks! Rewatch Value I'm not sure if I would rewatch this drama since I feel like there are several other dramas that better portrayed mystery/thriller genre. Perhaps one day I will revisit this! I heard the second season is much better so I have higher hopes for that one!
