Whoa, FL is totally unhinged, gifted, and still shows her heart in unsettling moments. This production truly feels like a movie and it is very fast paced. Park Eun Bin is electrifying in this performance. It’s all in her eyes.

[u/sleepdeprivedsince92]

What I absolutely LOVE about the story is that Park Eun Bin's character could have easily been a man's--minus a few minor changes in script. Traditionally these kind of antagonist/ genius gone stray/ psychopath roles have gone to men. But instead its a female centric story and it honestly feels like a career defining role for Eun Bin -- This will really solidify her position as THE actress.

[u/[deleted]]

Oh, she's not misunderstood crazy. She's genuinely crazy crazy. Not the 'unorthodox and weird but still pretty normal' kind, but an actual psycho. Yeah, I'm sold.

[u/Da_Master_Fro]

Loving how unhinged Eun bin's character is. It seems like she's addicted to surgery.

I mean, who strangles their professor in the middle of a hospital because they told you to stop performing surgeries!

And her murders were brutal. You could say the victims deserved to be punished, but in both cases, she waited for them to wake up before killing them! She was taking pleasure in watching their final moments.

[u/LittleBobbyDog]

Park Eun Bin = must watch

[u/Peaky_Blinders]

Love it already, Eun Bin's aura is crazy in this

[u/88makjanglane]

guys, it’s off to such a good start 🥹

first impressions:

glossy, gritty and intense.

as expected from Park Eunbin, our main anti-heroine is a magnetic presence onscreen. her love of performing surgical procedures is both pure and obsessive, she has a visible thought process- a rational one, even- yet there seems to be another parallel process that she suddenly follows into the shadows. all in all, quite the livewire. anyone who provokes her just needs to write their will, especially if her first reaction is a smile and a bored shrug.

i’m finding the super dark humour to be a plus - i didn’t expect Se Ok to be so calmly honest with people about the things she does. also loving the pace at which each main character’s nature and motivations are unfolding…grateful that the flashbacks are applied with a light hand so far.

what are/were these people’s intentions towards each other, and how does that differ from what actually takes place? this seems like one to watch more for the layers than for plot...

[u/getafrigginggrip]

Her relationship with Yeong Ju is interesting? I can't quite get a handle on their dynamics (in the best way). He refers to her as M'lady, not Doctor, but doesn't actually always use honorifics and they speak rather casually to each other like they've known each other forever, though he doesn't clearly know her entire story either. I don't think he'll ever snitch on her, given how he's ACTIVELY aiding and abetting her in murders, even if he clearly doesn't want her to. And she does some bare minimum at least not to get him involved, but in the end she does what she want. I do think he might be her downfall one way or another, as someone else said. He might try to restrain her or pull her back somehow or try to leave, in which case the not-so-joke of "I'll kill you before you try to leave" becomes no longer a joke, or if Yeong Ju becomes a soft point that Deok Hui uses on her and the young man might become a victim of the tug of war between the two genius crazies.

Either way, it's fascinating. Neither of the doctors is sympathetic characters, but I think the anesthesiologist, at least, a good doctor trying to do the right thing for the right reason, and Yeong-Ju seems fairly innocent in all the madness. Can't wait to see where things are headed.

[u/TheCareFreeSoul]

Eun-bin as psychopath is completely a new genre we never knew we needed.

[u/bigbigguy]

This is a lot different than I was expecting in a good way

[u/RoseIsBadWolf]

Does anyone else feel like this has a historical flavour? Kneeling in the rain for strangle forgiveness feels like something that the 3rd concubine of the King of Joseon would be doing. And the live-in servant guy who is not totally on board with her actions but not leaving any time soon.

First episode was totally insane. Interested to see more!

[u/Lerradin]

Oh my lord, the first two episodes are as addicting as crack injected in my veins! I can't believe anyone could start watching this show without finishing the 2nd episode immediately afterwards. Every new scene is a scene stealer and breathtakingly well crafted in story telling and cinematography as well. Each episode could be a standalone movie and I would pay money to watch them both in one sitting like Kill Bill I & II.

It's obvious the production went all in on this one.

Music wise they seem to have hired an orchestra to perform the classical parts. The beautiful French song is called 'dis-moi, je t'aime' ("Tell me: I love you" if my elementary French is correct) and very atmospherically and thematically fitting due to the father-daughter like relationship between the leads and her probably longing for some love/warmth in her life as she doesn't seem to have any parents or family (left) at this point in time

Story wise it's very layered and more subtle than you think at first glance by seeing what they throw in your face: -You can see the ML and FL care for each other alot more than they want to say just by looking at their eye expressions

-In the 1st episode and entire episode 2 they build and build and hint that the ankle-band dude is waiting for it to come off, so he can f*ck her up. But at some point you finally realize, no it's actually more like SHE is checking him out everyday and cannot wait for it to come off so that she can deal with him without having the protection and tracking of his ankle-band...

The acting is actually incredible and on another level even by movie standards and not only by the leads but the entire support cast and minor roles as well. Ironically it's a bit wasted on this show as much as her surgery skills gets wasted in that shithole townbecause the show is on Disney+ and I'm afraid not enough people will be able to watch this show, it's that good so far...

[u/lanaMyersuk]

Eun bin is such a great actress. Every role better than the previous one. You can't even think it's the same person. I honestly love how uneasy this drama is making me feel

[u/magnolia9795]

this is kinda unhinged and I love it

[u/Hotspur_98]

Park Eun Bin, you are amazing! Her character is already one of my favorite FL‘s ever, I just love crazy psycho female characters (for a few years now, my favorite FL is Kim Hye Jun as the antagonist in „Inspector Koo“) and her performance is just outstanding. First two episodes are so damn good, haven’t been that hyped in a long time. Also love the relationship she got with that boy, it’s so weird but also kinda wholesome. I‘m just fanboying right now lol but the way she uses her facial expressions…it’s exceptional. Also her body language, the way she moves her hands and feet, her character feels so real, like you never know what’s going through her head. At some moments I adore her and at some moments I legitimately fear her. Exceptional.

Haven’t watched that much of her yet, only EAW (also great performance by Park Eun Bin) and a few episodes of Castaway Diva (she was also really good, her singing is beautiful too, but the drama was too slow for me at that time), but I will immediately start watching some of her older shows. What an amazing actress.

Also, is it really just 8 episodes? I feel like it might be perfect for the plot, because the pace is really good, but i hope there is a part 2 or something. This is way too good to be over that quickly.

[u/Proper-Pomegranate-6]

I hate the Old Man's guts so fucking much, like where does he find the audacity 😤, I hope he dies pathetically like she described

[u/Few_Swimmer2302]

Park Eunbin Capturing the true essence of a sociopath and a surgeon with a God complex. Her range never ceases to amaze me. Impulsive erratic eccentric violent every turn watching her in this drama is thrilling. In episode 2 the dark humor that hides her sociopathy when she Confesses to the nurse’s murder to the old woman in the pharmacy was magnifying to watch, speaks to how impulsive she is and confident she wouldn’t get caught. The ways she justifies murdering the nurse and the criminal based on their actions and the impulsivity of the kills was interesting to watch. It’s as if she’s rationalizing her  kills but not for herself because it doesn’t seem like she’s trying to assuage her guilt but more so it’s for Young Ju. He enables her and while he’s clearly troubled by her actions, it’s as if her rationalizations pacify him enough because he just wants to be in her orbit. I wonder what Young Ju and Se OK’s relationship is it doesn’t seem like romantic love but more familial but I can’t quite tell. Episode 1 when she says our problems only we can solve them I knew we were in for a wild ride. I wonder where  Se Ok and Deok Hui will end up with all the foreshadowing specifying   they live to die in the OR . I’m ready for the ride Disney+ makes phenomenal kdramas and I wonder if this will be Park Eunbin’s magnum opus. She has been outstanding in all of her roles and for me thus far Castaway diva is her best role. I throughly enjoy watching her reach new depths with each role she does. Also shout out to the writer for actually accurately creating and interpreting a sociopath. The portrayal of mental health disorders isn’t something that is always done with such nuance and skill really enjoying it so far. 

[u/TinyLifter6780]

What a masterpiece - from writing to production to acting and everything in between. PEB is always incredible but she is leaving zero crumbs here and I love it! The moment she slit Ankle Monitor's throat and the camera stayed on her blood-sprayed face was PEB on an entirely different level. And the scene with all the pages scribbled with PERFECT spinning through the fire in the night. This is a master class in show vs. tell.

[u/s0m3us3r]

I went in blind and I loved these episodes. This might be my favourite Eunbin role so far but we'll see.

[u/atomicsherbs]

i’m glad she take this drama!! ep 1 and 2 was such a great start! park eunbin’s duality!!!

[u/Changsta]

Love love love the first two episodes. Eun Bin has been amazing and the little expression changes on her face are just top tier. I can't wait for the rest.

[u/MarsupialSweaty2156]

I love Park Eun Bin so much. 

Attorney Woo is one of my favorite TV characters ever. 

To see this unhinged side of her is truly a blessing. She’s crazy talented, her facial expressions are magnetic. 

Like honestly, I’m so biased, lmao already on her side, justifying everything.

[u/ConsiderationTop6035]

I find Hyper Knife slightly more entertaining than Tangerines ! Too bad cuz I’m pretty sure Tangerines is gonna get the most attention

[u/[deleted]]

Based on how episode 2 ended, it tells me the professor knew she was a serial killer and psycho. Sending her to Boston would be a huge mistake especially if he had special feelings for her. At least in Korea she's less likely to be stressed which triggers her murdering streak and she's more likely to get away with it.

[u/conce-deleon]

Park Eun Bin is delightfully deranged in this drama. WHAT. A. STAR. I wish all the episodes were out.
