Stranger (2017)

Both revolve around a mystery murder case and both are full of suspense and thriller from first episode to end. Got same feeling while watching both dramas.

Children of nobody points out the psychology, while Secret Forest is more to the politics, but I did spot some similarities
-Children of Nobody is much darker than Secret Forest but the crime cases occurred bcs of the quite similar 'perspective' that the character had, which make them be in ambiguous side (good/evil).
-The collab between ML and FL that are from different job.
-both are somehow melancholic on its own way

If very clever screenwriting is your weakness, look nowhere else! Both dramas share little in common in terms of the presentational contexts, but the power play twists and turns in both are really spectacular. Greed is a dominant theme in Stranger, but the villains in the The Crowned Clown mostly seek revenge. Stranger starts to pick up its pace from the end of episode 7 upwards, but The Crowned Clown has kept its suspense and momentum since the beginning. In particular, I found The Crowned Clown went a notch higher because of the magnificent portrayal of the dual characters by Yeo Jin Goo who has a very enigmatic screen presence, as well as the veteran actors who play the Enoch and his royal advisor.

Both dramas have an intriguing mysterious plot! In Whisper police investigation takes place but in a different way.Political corruption also dominates the drama!

Really intresting plot!!

Both drama are somewhat similar and have a great plot ....if u like signal highly recommend to watch "stranger/secret forest"

The main male leads remind me of each other in the way they hold themselves. Although the main character in the one does have the ability to express feelings. The settings and the plot stay professional throughout. The leads are also very smart and every move in the plot makes sense for each character.

Both complex thrillers play with the idea of power. Both are slow pacing dramas with unexpected twists and character dynamics. It gives the same feeling of suspense.

Law, investigation, and court focused
The lead character is seen as a person who has no mercy and very cold.
Another lead character is highly empathetic.
Most of the time their teamwork is on focus.
Very serious and dark vibes.

Secret Forest mirrors much of the work, themes and ideas of the power trilogy by Park Kyung Soo particularly Punch.

-In both dramas the plot revolves around solving a murder case
-the main male character both are centered around is around 40-50 years of age, intelligent and logical
-similar vibes throughout
-multiple and unexpected suspects
-plot is not heavy despite being focused around crimes (or maybe not the plot itself but the execution of the plot made them seem light? idk)
-LIKABLE CHARACTERS

Both are thriller/suspense dramas in a criminal/detective setting. They both are looking for a murderer, and deal with corruption and hidden organizations.

If you like the way Stranger is filmed, check out Awl. It's produced by the same company & I suspect it shares the same filming crew (at least to some extent). Both have very elegant, muted colour palette consistent through a whole runtime (greener in Awl, blue to light warm brown in Stranger). Music is limited mostly to background sounds and instrumentals and it's sparsely used, OSTs come mostly in ending credits, like a MV's teaser. Flashbacks are used for the sake of the storytelling, not filling the empty spaces to meet the time limit. Both are of excellent quality.
One of the main characters in both isn't very expressive and doesn't socialise much (in Stranger he's nearly emotionless due to a brain damage, in Awl it's just a way he is: gentle and rigid).
The topics are different, but hitting similar tones and both approach them with similar attitude: showing some kind of a corruption in a broad context, as a systematic, social failure based on relationships between humans. Stranger is sexier and wittier as it takes place between Prosecutor Office and Police and involves high officials and men in power, whereas Awl's more revolting (it showcases a conflict between a labour union and a mart's foreign executives), yet both have similar down-to-earth setup and problems are solved in a realistic pace.

Unexpected unpopular underdog rises to the occasion. Makes it work with the help of those around him.

Both dramas are expertly crafted so that the investigation slowly unfurls throughout the series until all the pieces start falling perfectly into place, making them even more enjoyable on second watching as you notice the subtle clues you missed.
Both tackle social issues.
To me it feels like they have a similar atmosphere.
Both will glue you to your seat.
