CONTENT WARNING: I hope you’ve already seen this movie and know what the deal is. But in case you don’t, I felt like I should add in a little warning. This show has mentions of suicide and death. And since this is a review, I do also talk about this (in relation to the movie only). Please be aware of that before you continue and be mindful of it. Stay safe ❤️

Simple Description

This movie is basically a psychological slap in the face. You think you know what’s going on  and then it flips the table and tells you, “Nope, that was all a lie.”

The Review

The Good

Twist After Twist After Twist

This movie knew how to play with your head  in the best way. The plot twists were so well done that I was second-guessing everything right alongside Jin Seok. When the brother got kidnapped and came back acting different? I was instantly suspicious. I had my own little theory board going in my head, and I was so sure Yoo Seok was the villain. I was wrong, obviously, but the ride to get there was so much fun.

Edge-of-Your-Seat Suspense

There were so many scenes that had me completely on edge. Like when the brother held the pencil right in front of Jin Seok’s eye , that was intense. Or the mysterious room with all those strange sounds. The best part was the feeling that everyone in the movie knew what was going on, except for Jin Seok and the audience. It made the whole experience so gripping. Unlike some thrillers that take ages to get interesting, this one had me hooked right from the beginning and never let go.

The Psychological Element

One of the craziest things about this movie is how realistic Jin Seok’s mental struggle was. It was something that can actually happen. While I’m no expert in psychology, I do know that when people experience extreme trauma, the brain sometimes can’t handle it and can block it out completely as a coping mechanism. I remember learning in high school that some people can go their entire lives without ever remembering a traumatic event. Therapy might help uncover it, but sometimes the brain even fabricates memories to fill in the gaps, leaving the real events completely buried.

And I’m not trying to scare anybody, but it really does make you look at Jin Seok’s situation differently. In Jin Seok’s case, I think it all came down to the fact that the family’s deaths were accidental. He never wanted to hurt them and  he was even ready to leave. But when things spiraled out of control and he caused their deaths by accident, his guilt was so overwhelming that his mind just shut it out. I feel like I should mention that I’m not justifying his actions in any way, it’s just so interesting to think about.

What’s even crazier is that he wasn’t “on the run” all these years, he genuinely didn’t remember what happened. And when his memories finally came flooding back, it made sense why his brain had locked them away. By the end, the guilt had completely consumed him, leaving him a shell of the person he once was.

This layer of psychological realism makes the movie even more fascinating  and honestly, so good!

A Tragic but Perfect Ending

Okay, this is gonna sound dark, but something about when a character dies right after getting what they wanted, makes the ending. It’s sad, yes — but also poetic. That’s exactly what happened here. Yoo Seok finally got the confession, completed his lifelong mission, and then ended his life. I’m not glorifying suicide, obviously, but narratively, it tied everything up in such a haunting, full-circle way. The story began with tragedy, and it ended with one too. It just… made sense.

No Time Wasted

One of the best things about Forgotten is that it gets right to the point. No drawn-out build-up or slow-burn nonsense. I watched this with my dad and stepmom,  both of whom have zero patience when a plot drags,  and even they were fully locked in from the jump. That’s how you know the pacing was done right.

The Bad

The House Was Just… There?

This didn’t even hit me until I was writing the description, but what was the actual point of Jin Seok being in that house? I get the obvious and that Yoo Seok planned everything to trap Jin Seok and get a confession, but the house barely played a role in helping him remember the murder. Jin Seok didn’t start recovering his memories until after he left and ended up in that interrogation/hospital room. So what was the point of having him live there? It felt like they were just messing with him for fun instead of using the space to trigger a sense of déjà vu or dropping subtle hints tied to the murder. The whole “playing house” setup came off as psychological manipulation without a real payoff.

Lack of Flow

I love a good mystery that keeps me guessing ,  but only if the clues were there all along. In Forgotten, the twist works because it blindsides you — but maybe too much. We weren’t just left in the dark, we were locked in a pitch-black basement with no flashlight. The murder plot came out of nowhere because there were zero hints leading to it. We were busy debating between “A” and “B,” only to find out the answer was “R,” — which we didn’t even know was an option.

Take the kidnapping, for example. It was juicy, sure, but what was the point? Why couldn’t Yoo Seok just say he needed to leave for a while? The kidnapping didn’t tie into Jin Seok’s memories or the murder at all. If it had triggered flashbacks, then it would’ve felt more intentional, but instead, it was just there.

And what was up with the brother’s personality switch? When Yoo Seok returned, he acted totally different — but it once again didn’t connect to the murder storyline. It just felt like a wasted detail. Yoo Seok was supposed to be pulling off this genius plan to get Jin Seok to confess, but halfway through, it’s like he stopped trying. The movie was so focused on making the brother seem suspicious that they forgot the whole point was getting a confession. Jin Seok didn’t even have a cool “aha” moment where it all tied back to the house,  it was just some pictures and therapy. If they wanted to really mess with his head, they could’ve done it in a way that was darker, longer, and tied more to the house.

Plot Overload

This one’s quick because I kinda already said it, but still,  Forgotten felt like it couldn’t decide what kind of story it wanted to be. The movie felt torn between two big plots: the brother’s kidnapping and the murder. They were both treated like main events, but one had to take a backseat  and that’s what happened.

At first, the house was the problem. Then it shifted to the brother being the problem. By the end, we learned Jin Seok was the real and only problem. These are all huge storylines, and instead of layering them meaningfully, they kind of just threw them at us in phases. If you’re juggling plots this big, you’ve got to decide which one is the main story and make the others smaller subplots. The kidnapping had way too much attention for something that ended up being insignificant. Maybe next time, they could stick to one big plot, stretch the runtime, or split the story into multiple movies to flesh everything out properly.

The Trailer Lied (a little)

Okay, this isn’t a huge deal, but the trailer was kind of misleading. The trailer heavily sold this as a “my-brother-isn’t-my-brother” thriller, only for that to not even be the main storyline. Definitely had me fooled for a bit and I’m glad the storyline was good despite this or we would’ve had problems.

What I Would Do

Pick a Lane and Drive It All the Way

Like I mentioned earlier, one of the film’s biggest flaws was trying to juggle too many main plots. The house, the brother, the kidnapping, the murder — there was just too much going on for one to shine. Since the murder was clearly the real core of the story, I would’ve leaned into that from the jump. That doesn’t mean spoiling it early, but giving just enough hints so when the reveal hits, it feels earned and  not random. Here’s how I’d rework that:

Breadcrumbs Galore:

If the murder was the main twist, I’d leave small clues sprinkled throughout — just enough to make you think “it was there all along, we just didn’t notice.” on rewatch. The “family” could drop weird lines that don’t quite fit. The landlady (who I’d add and would also an actor in my version) would’ve been part of the set up. The family could mention how she’s been there for years and knew about the previous family’s tragic death. The landlady would mention strange details that Jin Seok subconsciously recognises. Maybe he accidentally finds an old article about the crime, or sees a photo that weirdly unsettles him. Just little red flags that build tension over time, instead of dropping the whole truth like a bucket of cold water in the third act.

The House Would Feel Familiar:

Since the house itself is such a key part of the murder, I’d make it a bigger player in the story. If Jin Seok committed the murder in that house, it should haunt him — even before he remembers. From the first moment he steps inside, he should feel like something’s off. Not in a horror way, but in that creepy, “Have I been here before?” kind of way. That tension should build day by day  with  random moments, eerie feelings, and flashes of something forgotten.

And then finally , when things start to unravel, his memory snaps back in a big scene. Maybe he’s triggered by something the “brother” says. He rushes to the locked room, expecting answers and, this time, it’s not a surveillance room like before. It’s the room. The exact room where it all happened. The layout, the bloodstains (faded but still visible), the same eerie quiet. That room would serve as the final puzzle piece to unlock his memories. It would be such a powerful full-circle moment and way more impactful than just showing him pictures and saying, “You did this, remember?”

Final Thoughts

Like I said in my previous review, this movie is one of my top-rated dramas. I absolutely love psychological thrillers, and this movie really knew how to deliver. From the constant twists to that hauntingly poetic ending, it had me hooked from start to finish. It’s no surprise I gave it a solid 9.0/10.

That said, once you peel back the layers and look a bit closer, you start noticing the cracks — like the multiple main plots fighting for the spotlight, or a kidnapping arc that ended up doing nothing but confuse everyone. It’s one of those films where your first watch is a wild ride, but your second has you raising your eyebrows a few times.

Still, no movie is perfect, and this one delivered where it really mattered. It’s one of those thrillers you wish you could experience again for the first time. And if you do decide to rewatch it, just don’t think too hard about the plot holes  and  do what I did: dramatically gasp, pretend you didn’t see them, and keep the popcorn coming!
