This was my first ever Light On series to watch because though I do like the whodunnits and CSI type series, they never spoke to me before. But because I follow and highly respect Zhao Liying, plus this was such a different role for her from what she'd previously done, it intrigued me even more. The only other actor I have seen previously was Geng Le (Li Lan) but he only had a bit part and was killed off in the first episode.

Pros: I knew this was only a 16 episode series though these Light On ones were usually 12, so I felt that 4 extra episodes were a bonus. I loved the richness of the actual story and how within the first 3 or 4 episodes, all 3 characters had come into there own. I think this genre really suits ZLY because she fits the creepy sociopath very well. She was so convincing at times that, it honestly almost made your skin crawl. I've done my share of research (close to a decade) on serial killers, their psychopathy, and crimes and each had different Modus Operandi. I was very interested in which angle they would take with this one.

Episode 12 gave a serious shock but a very, appropriate cliffhanger that shifted the entire case and story in a completely different and unexpected direction. I think that was my favorite part. As a novelist, I've written many cliffhangers, so getting one that was that well written and executed was rare in cdramas.

I loved the interconnections with the leads and those in their everyday lives. They were all portrayed as very flawed and at times quite selfish individuals. It spoke of the rawness of humanity at our bad or worst times and yet at some moments they showed the best of us. Every emotion from fear, anger, sadness, despair, obsession, helplessness, determination, and so forth was shown in nearly every episode. Even if all three were in a sense going towards the same goal; finding the truth, they still managed to do it separately which many a time worked and other times seemed a bit off.

One thing that the series never lacked was just rawness; whether it was in emotion, action, or dialogue. The simplest "how are you" like when XM visits SY in jail in the last episode carried with it a seemingly 17 year burden of truth both characters must forever carry, though they both found out their own versions of truth. The series was powerful and nothing could be taken away from that.

Cons: For starters, there were several inconsistencies and disconnections that were never answered or corrected. Like why did SY's father get so angry at Hu that he beat him up, making the latter leave the hospital and than when little SY asked her father who Hu was in the library, her father was very angry that she asked and that was just left alone. SY's friend in the wheelchair seems to be important but he appears and disappears without fanfare and we literally know nothing about him, which is quite odd considering how SY literally had no other friends.

Both SY and XM seemed to have very lackadaisical schedules where they could walk in and out of their respective places of employment whenever and do whatever they wanted. It was rather strange how much a rookie cop was able to get away with during his own private detective work. Why had SY been able to get away with everything else she had done aside from sending the poor man falsely accused into a coma? Also, the very much unneeded psychological warfare on XM and how doctors just handed out patient information without notifying the patient for consent. Another point, how did SY's father know where the murderer was during the XJ murder? Out of the entire city he just happened to walk by him there and recognized him in a mask and cap after not seeing him for many years? Zilch cohesion.

The reveal of the actual murderer was a bit underwhelming because there was this huge lead up after the bombshell at the end of 12 but it didn't deliver the wham of the killer. His confession was typical obsessed psychopath with a one sided relationship with his victims story; a rookie profiler fresh out of Quantico (school for future FBI agents) could have done better. Even his reasoning wasn't imaginative, though he made it sound very sinister (hats off to the actor). Now I'm not saying all serial killers look like monsters; as a matter fact more often then not, they look like your next door neighbor. It wasn't about the looks, but about how he was cornered, in a restaurant that allowed a random stranger who'd slept amongst their trash the night before cook dishes in their kitchen? Come on now, that's not even soap opera writing. It felt like the writers were just tired of this story and wanted to add just random components into it and hope something clicked. It could have been done so much better to make for a satisfactory ending.

Lastly, there were times in the middle that the episodes did get draggy but then they righted themselves. This series could have stood to explore the pathology of criminals a bit more to make up for the inconsistencies and lack of cohesion in many places.

Still though, I think this is a very strong series and I would recommend it to both people who enjoy crime dramas and fans of ZLY who want to see her do really well in this dark and gritty role.
