I haven't seen the Japanese source material for The Smile Has Left Your Eyes, but I don't think any of my criticisms here would be ameliorated had I seen that version beforehand. I guess it's possible for me to exonerate the South Korean version of its faults and just attribute every outrageous plot point to bad writing elsewhere, but for the love of the gods above, can't we get an adaptation that improves upon its source rather than a beat-for-beat reconstruction of popular garbage just because?

Here's where I provide full disclosure: I only started watching this because I generally like Seo In Guk's work, and I've liked several other cast members' work in other dramas. I don't seek out the thriller and mystery genres, I tend to stick with art house cinema or comedy romance shows, and I stray out of those areas when I feel like I'll be rewarded for experimenting or when I'm feeling tired of the same obscurantist shit or poorly written bubbly junk food. This show was unbelievable, and it was unpleasant, and it encouraged me to return to my usual fare for a while.

Spoilers, obviously. If you haven't clicked out, this is your final chance.

The characters' motivations, actions, and the consequences (or lack thereof) were outlandish to the point of offense. Irrespective of Moo Young and Yoo Jin's uncontrollable lust for one another, the fact that Yoo Jin even entertains the idea of shacking up with Moo Young after he emotionally cheated on her best friend WITH YOO JIN and openly bore some responsibility for her death is LUDICROUS. Moo Young's infuriating antagonism when he's being investigated in a murder case is absolutely insane. That Yoo Jin was even willing to be in the same room as her brother after he stabbed her super special boyfriend and miraculously didn't even lose his cop job is incredibly ridiculous. Why did Yoo Jin agree to date Moo Young ONLY on the condition that he actively self-improve, and neglect to provide any sort of schema or apparatus for Moo Young to achieve whatever it is she's envisioning, if she was just going to essentially drop the subject entirely as Moo Young continues to lie to her? Why does her character turn from observant and assertive to naïve and acquiescent to the whims of the guys?

I couldn't buy into the drama, because the premises and conclusions were nonsensical and inconsistent. The people in this universe don't seem to understand the weight of others' transgressions, or else SOMEONE in the police department would have pulled Jin Kang's murderous stabby-mc-stabber brother in for questioning. I don't know any decent person who would get involved with their dead BFF's unfaithful, manipulative ex. Even a sociopath would know that they have to make some claim to their innocence when a cop starts stalking them. It's like the showrunners thought that suspense equates with whimsical, destructive, unchecked trickery on the part of the characters.

Stories only remain suspenseful insofar as the viewer can suspend their disbelief and immerse themselves in the urgency of the situation. But nothing here had any repercussions until everyone started shooting each other. The moment some threat was posed to any of the main or supporting characters, it was immediately quelled by folks who are disturbingly comfortable with their loved ones' violent urges or that thread was dropped entirely. Yoo Jin would be in fucking therapy for what went down with Seung Ah, is what I'm saying. Sleeping with a dude your friend fucked is awkward enough, never mind the weird-ass sociopathic shit and the death.

I couldn't buy into anything this show was selling. Basically, its overarching mysteries were boring and predictable (obviously Moo Young isn't the killer??? He's not the one stalking random people?? You can clock most of the murderers in this show based on how many people they're stalking until episode 15) and its twists were so stupid that they divested from whatever wisp of a suspenseful tone the rest of the plot succeeds at sowing. The whole thing plays out like a sensationalist novel that started out as erotic fan fiction on the internet. It's like there's no need to reconcile the various parts within the whole because it's more important to use to just throw out whatever shocking crap we can to keep people tuning in every week.

The sixteen episode standard didn't benefit this narrative either. It DRAGGED, and from what I understand, the Japanese version was only 10 episodes long. Cut the flashbacks, cut the repetitive conversational loops and cut to the chase: are these sociopathic weirdos gonna bang or nah? That's infinitely more intriguing than drawn out conversations while people sit around tables and cry intermittently, running in and out of that top-floor apartment incessantly because we couldn't afford another set.

Waiting for Moo Young and Yoo Jin to finally seal the deal was excruciating, because they had to play out a coy dance as if Yoo Jin ACTUALLY cared about Seung Ah, as if anyone was actually thinking about Seung Ah (including the writers). Yoo Jin had a thousand chances to be a good friend, or a decent human, to Seung Ah before she finally agrees to bang Moo Young, and she never rose to the occasion, so I don't understand why there had to be this pretense that Yoo Jin was conflicted for eight episodes when she clearly wasn't??? She literally sexed her dead best friend's boyfriend like two days after she died??? So cut four of those episodes out! Seung Ah dies, boom, we get the nookie. There you go. Millions of dollars, saved.

Oh, I figured it out - the real monster is Yoo Jin. She pretends to have emotions and morals, meanwhile she somehow pulls together a bunch of murderous wankers to annihilate her messianic, perfect, lovely friend before they burn the world down, and her with it.

I feel like I wasted my life. I'm giving this a 10 in rewatch value because I think it'll be great material for a drinking game with my friends.
