I'll be honest, I'm not interested in crime thrillers, I much prefer romance dramas but I watched this purely because of Lee Joon-Gi (the lead actor). I watched him in Moon Lovers the week before and was mesmerised so I wanted to see more of him and support his projects. Well, if you're like me and hoping to find Prince Wang So in here then don't watch this. There is no chivalrous, cool, calm, overly handsome, deeply in love Prince... but there is an apathetic psychopath that still gets you hooked.
DEFINTELY WATCH THIS IF YOU WANT TO SEE GREAT ACTING FROM LEE JOON GI.
He also plays a loving husband and doting father which takes him to another level of hotness.
The storyline is gripping! I'm usually good at guessing the outcome but even i was blind-sided many times. The amount of twists in this series is out of control. In my opinion, the writers should have left out the last twist so it could have been a much happier and satisfying ending (and I would've given it a 10 star rating).
Therr were a couple of touching scenes were not so touching, felt a little overacting...like when they hug and cry, I felt like they were over-hugging and over-crying, however it's completely forgiven because I'm obsessed with Lee Joon Gi.
Overall, a very riveting series that will keep you on edge, you will enjoy it if you're into crime/suspense thrillers (think The Bone Collector style). Not as addictive as Moon Lovers if you're into Romance however a must watch if you want to see kissing scenes from Lee Joon Gi and imagine him as a hubby.
