First of all.I put the Spoiler Tag but don't be afraid.Iam not giving away any important detail.Just my thoughts about some scenes,which were way too absurd and nonsensical,in a very vague way.

Do i recommend this Drama?
Short answer is NO.Absolutely NOT!
As for the long answer..Well keep reading.

What i liked:
Good Production quality,nice Cinematography and beautiful Osts.I really loved both intro & outro songs(hence my 9 stars)
Yes,iam done with the good part.
Let's move on.

After watching the first episode i was already conflicted about the drama.I should have known better.The first impression is always important!

Cast/Acting:
Oh my!Where do i start..
Half of the actors were seriously miscasted.And few of them really do not deserve so bad written roles.
I made a short comment in the feeds, few days ago,after watching the 1st ep.I copy/paste :

"Iam not familiar with the 2 male leads but the rest of the cast is Top so i guess it won't be any issue regarding Acting."

Iam taking all back...Better chew than talk,maybe?lol

When i saw Jung Sang-hoon was one of the mains i was so happy because he is one of my biases.And to be honest he was one of the reasons i started it in first place.
I loved every role he played.Ive enjoyed his acting every single time.Here ,it was a pain to watch.
I don't know if the actors had full liberty to act as they pleased or were under director's full and strict guidelines.
Either way,acting was mediocre at best and bad most of the times.

The Drama is full of(wannabe)emotional moments and the actors were supposed to convey all those emotions through their lines,their expressions,body language etc.This is what an actor does,right?Well i assure you i can show more genuine emotions and shed some real tears better than them.Harsh comment but true.
And i do know they are good actors as ive seen them in other dramas.I know they have talent.Here i cannot put my finger on what was wrong.I guess is a combination of bad direction and bad writing.

Characters:
Half of the characters were portrayed like clowns.Too many annoying and silly chars,most of them added nothing to the story.Like seriously,apart the 6 mains who were the base of the story,the rest were decorative.
Also towards the end a new character was thrown out of the blue.I wish i could open writers heads to see what the heck they were thinking.
The only mature and really likeable was the little brother.And guess what!He had the least screen time!Go figure!

Story:
The main idea was excellent.The story was interesting.And yes,the cliché conclusion is that the execution was bad.Bad,, bad REALLY BAD!
The story is like scattered pieces picked periodically by the leads during the drama and then they acted like had no idea about what to do with these pieces or totally forgot them.

And here is the main reason iam too bitchy and nagging so much about this series!

Genres: Action, Thriller, Mystery, Drama..

A crime/mystery drama having more silly moments than a verified Comedy,is too much to take.Its something i can't easily digest.Iam not talking about the necessary scenes with a comical touch to relief any tension.Iam talking about those over the top ridiculous moments to make you shake your head and pull your hair too.
I had so many "WTF" while watching..
Please tell me who nowadays finds a fart scene funny??Seriously is there anyone?

Also the amount of stupid decisions made by almost every character,is ridiculously high.
Not to mention the usual incompetence of the police force,including our main detective lead.
Who,under certain circumstances was in a bad shape,but still after finding a very important physical evidence,he just safekeeping it for a year and after he has a delayed... epiphany and thought to search it further.My poor walls had to put up with me and my screams!
I hate(well, not like)Romance but most of all i hate forced romance.No chemistry whatsoever between the leads.And also be careful who you ship with whom..
Again one of those unnecessary romantic plots for the sake of having a non-tagged romance.I can't.


A mild and so-called spoiler:

One of the biggest "WTF" was the scene where inside the interrogation room,a prosecutor gives to a murderer a knife and a fork to enjoy his steak.Oh!the murderer is without handcuffs too!Bravo!Such a smart move!

I can continue and write so much more but i don't want to spoil the fun for you.Lol!
Iam sorry i may sound bitchy and rude but this is not inspiring or creative writing.Its just..sloppy.
When the writers themselves dont have a clear path about their story how do they expect the viewers to like and support it?
I couldn't.

Suggested overall: 5.5 Iam a big heart!Im giving this a 6!

Seriously i must find the courage and start dropping dramas because i can't continue like this!
