This is a dark series. And not "dark" in comparison to most Korean dramas, dark as in real life, traumatic dark. It's no surprise that this was originally a Japanese series but I'm glad it was adapted nonetheless as it was magnificently made with no holding back with the subject matter, tone of the series and ending.

'The Smile Has Left Your Eyes' from the very first episode presented itself with a protagonist who has very little inhibitions or care about the people around him. Our very first look at Moo Young, we are exposed to a cold man with dead, empty eyes. So much that our other male protagonist, Jin Gook, defines him a monster, evil, un-human. Moo Young is, indeed, an anti-hero but not a cliched one either. He is a deep, multi-layered case study on the hardships of life and what an effect childhood has. Jin Gook has a dark past himself, and steps over the line deep into the series, doing something unthinkable and reprehensible despite being the moral figure of the series, so perhaps he isn't the best person to judge. Jin Kang, sister of Jin Gook, love interest of Moo Young, is the most innocent of the free but she isn't scar freed herself. All three characters are in their own ways hurt by the world and the events that happen throughout the series - death, loss, murder, etc. We may look at the romances as some palate cleanser to all the darkness surrounding it but as we delve deeper into both Moo Young's relationships with Seung Ah - a fun, freeing relationship albeit a one sided one - and Jin Kang - a healing one and a hurtful one, we learn that it's too destined for a terrible ended. Ill- fated love is definitely a main theme that 'The Smile Has Left Your Eyes' explores. 'The Smile Has Left Your Eyes' is an excellently developed series with twists and turns that are all plausible and done in such a thrilling yet harsh way. You'll get hooked from scene one and might actually regret it at the end.

The cast was excellent and while at sometimes, character disapear and we never see of them again or we are treated to very limited apperances from said character, it never detracts of the main story that's built around the main three (maybe add Jang Young Nam's character, So Jung in on that trio as well). I feel like everyone served their purpose. Seo In Guk is gripping with his scenes and how he delivered his lines in such a way that captures the character's emotions perfectly while actually doing very little. How he interacts with Jung So Min is both heart-warming and heart-breaking. Same with Seo Eun Soo ( Seung Ah) actually. There relationship is a one that could've made us, the audience, turn against the character, but they were able to portray the complexity of the situation and their relationship real well. Jung So Min and Park Sung Woong were great together. Bonded like Brother and Sister should be. Themes aside, I felt like this would be my sister and I's relationship fully. Park Sung Woong and Seo In Guk's characters were the opposite but intertwined at the same time. There was a lot of subtle to it. Both had light and darkness. That speaks volumes to their performances. I'll end with this; the main three should've won some awards for their performances, and I don't usually say that.

Must-see for anyone.
