Pram Nov 10 2025 5:15 am For those who said Jang Ha Bin is very stubborn & annoying. Because she is very smart (remember when her teacher told her dad she helped the male Lee soohyun behind his back? Because she knew he was financially struggling) but unfortunately she dont trust anyone especially her own dad. Her father just forced to lived with her after her mother took her own life.

I want to write more bit it would be a spoiler. When someone is very smart but also sceptical, she will also become more stubborn than others. I'm just glad slowly she can finally open her heart to her dad.

Pram Nov 10 2025 4:50 am I love psychological drama like this! It invites the viewers to analyze the situation and guess who's the real culprit. And my guess is not any different than the dad. Very recommended for those who love psychological + crime drama. I love how the good people can finally beat the psychotic manipulative trick of the perp in this drama. Must watch.

Nadia Oct 10 2025 6:59 am This is a slow-burn drama. As someone who loves mystery/crime series, I find the pace way too slow, and the mostly dark background setting doesn't help, it's quite depressing. But, as you watch, you become intrigued by what is going on and want to know more. Did anyone else notice that Jang Tae Soo only wears blue long-sleeved shirts and only changes to a beige jumper in the final episode? I wish we had got some closure on how Ha Bin's younger brother died, but I assume it was an accident. Maybe he fell off a cliff while playing hide-and-seek.

Ging Sep 03 2025 3:36 am Scenes are so slow and dragging! Not recommendable!

John Aug 27 2025 8:19 am Personally I feel the episodes of this drama are confusing and repetitive, making it frustrating to watch. Pacing feels unnecessarily drawn-out, which makes me restless.

Magda USA Jun 15 2025 4:57 pm Wow! ? what an incredibly great series! Great Plot! Great acting from ALL actors and actress! Yes! Kind of slow at times, but so worth watching it! I love Who Done it? Mysteries, especially British like Vera, Endeavor and many good American shows as well. But after watching this and before watching Stranger 1 and 2, South Korea is great at these shows as well! Highly recommend it!

elliemae207 Mar 07 2025 2:18 am I think I can see why the ratings are not that high. This series has a good storyline, but the episodes are dragging. I feel as though this could have been made into a two-and-a-half-hour movie instead of just going around in circles to complete 10 episodes, in my opinion. At any rate, Han Suk-kyu nailed his character here. I've liked him since Dr. Romantic, and he delivers here in "Doubt" once again! Hwighting!!

noi Dec 27 2024 3:52 am Habin Clearly had trauma from her brother's death. The way both her parents didn't take her to therapy and instead walking around on their toes while keeping their doubts is the biggest mistake. And what? They expect her to have normal life and friends around her age? Her mom went to therapy alone instead and left Habin dealt with her own trauma? This is soo frustrating. You guys annoyed at Habin? I'm more annoyed with her parents. If you can't bear consequence being parents, just don't be.

Kdramastan Dec 22 2024 11:06 am Han suk kyu and officer Gu nailed their roles. the daughter was annoying .very well written show did drag at times but absolutely worth watchinh

NGS Dec 14 2024 4:08 pm I am trying to understand EoJin all the time that she just do her work, but She Is Annoying. This also the answer why intially they just want to hire only DaeHong

Anita M Brown Dec 14 2024 8:13 am Suspense, mystery, action are my fave genres and this is totally suspense. Love this drama. Not a big fan of minimal stage/sets, but just as Perfect Family, Doubt works very well. Great drama and I am hooked after the first episode. I like dramas that make me think higher and I will have to repeat the first episode and really pay attention. Doubt is the drama experience I love most.

Anylee Nov 24 2024 9:52 am Its interesting, slow paced and frustrating at times. I'm not hooked yet but I'm curious about how things will turn out.

Fayfa Nov 22 2024 5:19 pm U need to watch this drama, a rollercoaster for emotions...

Zephyr Nov 17 2024 12:20 pm If there is a drama or story with a perfect writing, this is the one. well written, it explain every plot hole that come is my mind and usually the last 3 episode crime series will revealed the answer one by one, but not in this one, you still doubt everything even till last episode. I think this is one of the best series in 2024.

Hoosierr Nov 16 2024 9:11 am Everything is very well done. Suspense, emotional arc bw father and daughter. Show plays w our suspicions till the end. However i believe this script would work much better as a 2 hour long movie bc at some point it feels like drawing circles just to fill 10 episodes.

wnnny Nov 15 2024 10:54 pm Jang Tae-Soo led the Criminal Behavioral Analysis Team and supervisor of profiler Lee Eo-Jin. However, she simultaneously reports to Oh Jung-Hwan of Police Violent Crimes Team 1. As such, in my opinion, Lee Eo-Jin must be suspended and transferred from the Criminal Behavioral Analysis Team and the Police Violent Crimes Team 1 due to her insubordination.

wnnny Nov 15 2024 10:47 pm @Taec, how do you know the viewer(s) did not watch the drama carefully (quote your comment "............. "(proof that they didn't watch the drama carefully)." Every viewer can state their view after watching each ep /drama in this webpage as it asks for Comments!

Audreya-Lynne Nov 15 2024 7:57 pm I'm currently on episode 7 and Lee Eo-jin is pissing me tf off. Like girl mind the business that pays you(Yes I know she is just doing her job but DAMN she's annoying) Now Gu Dae-hong is a sweetheart. Ha-bin is also pissing me off. Like girl, just let your dad help you. It's like she wants to end up in prison.I'm solely seeing this drama to the end for Han Suk-kyu and Han Suk-kyu ALONE. Everyone else in unbearable(minus the runaway gang, there acting is fine giving the small amount of screentime they recieve)

Taec Nov 15 2024 4:57 pm I have watched over 200 kdramas. This is the best. The writing and direction is top notch. I loved the character Ha-bin from start to finish. She is such a lovely and well written character. I loved how the drama focused solely on 'doubt' till the end. Really got to know everything related to doubt. I liked how the drama tried to test it's viewers in the 9th episode. I'm glad that I didn't fall for the test. I'm glad I learned to never doubt Ha bin as that was the main lesson each episode taught us. The direction was brilliant, it was not at all laggy. It was very fun and engaging to watch. Please don't listen to the people who complaint it is laggy,as it's the same people who say they hate Habin (proof that they didn't watch the drama carefully).

laura Nov 15 2024 11:55 am dark but also warm.. so good♥️

Nesrine Nov 14 2024 12:55 pm Can't wait for the final episode this serie is crazy

daisy Nov 13 2024 9:03 pm I thought i'm the only one hated Jang Ha Bin character

wnnny Nov 09 2024 10:58 pm I watch this drama because of Han Suk-Kyu.

In this drama, the story line is interesting; Jang Tae-Soo is fulfilling his role as Jan Tae-Soo; The profiler Lee Eo-Jin is not fulfilling her role as profiler, Lee Eo-Jin is more of a detective role, she has no respect for her supervisor Jang Tae-Soo, and she thinks she is always right, arrogant. I hope Lee Eo-Jin will be suspended and transfer to be a road traffic police, or further profiler training.

Jang Ha-Bin is quite stupid!

Supanika Nov 09 2024 1:26 am At first the plot is kinda interesting but they dragged the story and tried to make it complicated waaaaaaaaaaaaaaaaaay too hard. To the point where it felt so slow and boring.

titi Nov 06 2024 1:22 pm Whether it's right or wrong, just leave Ha Bin in prison! At least he made the audience emotional and stressed with his stubborn attitude

. makes the audience dizzy and annoyed, I even forgot the heinous crimes committed by the original villain... it's a shame that this wasn't explored more deeply... please writer, make less dramas like this... with disobedient children

May Nov 06 2024 12:55 am Tho the lead actors and support are good the story drags with Too long pauses to a pont it gets boring and annoying.

hHa Nov 05 2024 10:08 am all the messs is because ha bin..

Millie Nov 05 2024 5:26 am The story in the beginning looks interesting but the daughter’s character is quite annoying. She went all the way to the teacher’s father to touch everything inside, i mean that is so dummy of her to do that knowing that her father is a profiler. And she should just stay put if she is not the killer.

Purple Nov 04 2024 3:45 pm Only here because of Kim Sa-boo. I can't count how many times I've rolled my eyes because of the daughter's stubbornness. Her pretend bravery and arrogance makes her really annoying. Add up the smug and poker face. Jeez. If it wasn't because of Han Suk-kyu, I wouldn't even bother watching till EP7.

Binda Nov 04 2024 7:04 am Watching this at 1.5x speed yet still slow? currently on episode 5 what the heck will happen!?

Best crime? WTF Nov 03 2024 8:10 am The story's not bad, but some characters really mess things up.

The father-daughter duo feels way over the top, like the typical Korean drama trying too hard to make the leads look cool.

Habin’s just a regular girl, and honestly, without any plot armor, her crazy bravery would have gotten her killed by now.

And then there's Mr. Jang, who's supposed to be a pro. Seriously, he could have done so much to keep Habin from messing up the police investigation even more. He’s meant to be the best profiler, but he acts so foolishly in these situations.

Lara Nov 03 2024 3:48 am Currently watching ep 7 and I have to say that this is one of the best crime drama this year. The tittle really suit our feelings when watching each eps. There is always a plot twist in each eps, really good. Looking forward to know how this gonna end.

Sky Nov 01 2024 8:39 pm Best crime drama so far.. every episode is interesting that make you will not skip every scene. Jang tae su is so good and his daughter too is so good in acting.. 10 episode doesn't enough tbh. Recommend drama.

Doubt Oct 31 2024 3:54 am Ha-Bin is taking revenge to the gang leader that killed her friend Su Hyeon.

Shairli Oct 30 2024 8:48 am Really hate Jang Ha-bin character. Even if she is good (yet to finish the series) she irritates me. Prefer her to be the real criminal.

Kristine Oct 27 2024 7:29 pm Wow!

I can see why the guy was getting the job and not the female detective.

My guess is the teacher killed the girl. The woman got the gang to blackmail the mom into thinking the daughter did it. The teacher keeps lying. I think the daughter is trying to get back at the gang for blackmailing the mom? I think the daughter is weird but not the killer.

I want that small child removed from that woman’s house. My goodness.

Aespa Oct 26 2024 4:53 pm The Worst character is female cop... She is too annoying

Hh Oct 26 2024 1:53 pm I hate Lee Eo Jin!!! She always feels like she is superior, knows the best. Gosh, really worst!

Sarah Oct 23 2024 7:57 am The drama is amazing one of the best so far in 2024 i hope it got morw popular, the writer and the cast are amazing. It's not easy to predict what will happen next. Cant wait for the rest of episodes

Calico Oct 20 2024 4:18 pm Jang Ha-Bin makes you doubt her with her blank stare, making her father Jang Tae-Soo go crazy because he can't read her. The ending of episode 4 makes you really doubt that was it all this time she was finding out why Choi Young-Min was black mailing her mom. Is it why she had to kill Song Min-A to get information....hmm makes you see her in a different light. I am hook!

세리나 Oct 20 2024 7:42 am So far soooo good! Can't really predict what's coming next.

Hhh Oct 19 2024 4:21 pm I think the mom didn't kill the girl, but the mom probably thinks that ha bin killed his friend. She wants to protect ha bin, so he tried to buried her like that. Maybe ... Haha

enjeans Oct 19 2024 2:23 pm The story and whole drama really lives up to the title, "Doubt." After watching ep 4, I really couldn't tell who murdered who and what is actually going on because I doubt Habin, the gangster, the homeroom teacher, and the lady with the kid. Like, What Is Going On?! I literally have no clue what is going on and that's just amazing lol. I can't wait for the next ep and I regretted watching this while it's still running because the curiosity is kiIIing me hahaah

detective Oct 19 2024 1:11 pm after ep4 i cnt really tell who killed who now. could be ha bin was trying to find out who killed the bestfriend and the reason her mom end her own life? too much uncertainty goin around in this drama. bt overall it is rly a good thriller drama

jin Oct 19 2024 1:04 pm prob plot twist after watching ep.4. maybe ha bins mom killed shu hyon and choi young min somehow saw it tht was why he blackmailed and threated her mom. nt sure of the reason need to watch more. and who knows actually min-a wasnt dead?? lol cant wait to watch next episode.

Habin Lover Oct 18 2024 8:52 pm Go habin go...you've inspired me into doing the same as you do...thanks

Kristine Oct 17 2024 2:21 pm Loved first episode. Wonder why not much love. I hope it does well.

Riri BlaQ Oct 15 2024 4:29 pm The first two episodes got me on my toes. What??? It's so interesting, just the thriller I needed in my life right now

Cey Oct 13 2024 1:13 pm God she’s so annoying

pearl Oct 13 2024 5:44 am Love the acting of Han Suk Kyu, such a legend and his co star. love the story, feels exciting to follow the plot. Fighting!

mt Oct 13 2024 2:15 am I hate this draggy feeling... i cant stand the daughter.. i seriously hope she is the murderer for Min-A and her brother and she gets to jail

Anna Oct 13 2024 12:44 am Looks intriguing.but its story line ,kinda close to taiwanese drama Victims's Game.forensic guy doing his best to protect his daughter. Evidence points to his daughter, but he hides it.

The Psycho Oct 13 2024 12:35 am Think...if there's no twists...ha bin should be a born psychopath....but I hope otherwise

Blooms Oct 12 2024 10:57 am I'm going crazy, Habin so dangerous, she's killed his brother?!

Your Honor x Black Out more stress!!!!

Ann Oct 12 2024 8:27 am What a spectacular 1st episode. This is The Best Drama of the year, I know it's just one episode but the cinematography, the script, the acting, the sound are top notch. I got chills at the end of ep, I need all episodes Now. Note this, this is going to win the Baeksang Drama of 2025. Writernim, directornim, cast & crew, my humble respect and keep up the amazing job. Doubt Fighting!

heusi Oct 12 2024 1:46 am so its like “Your Honor” 2024 also????

... Sep 08 2024 4:03 am She was so good in villainous role

Aimen Jul 30 2024 3:28 am Oooooo, the trailer is FIYAH...gonna love it
