In my point of view,I think "legend of the blue sea " is one of the underrated dramas but that was so good. What yours?

Underrated drama

On the way to the airport

Black

The Producers


Underrated movie: 

Sunflower (Kim Rae Won)

In my opinion - Madame Antoine... I remember liking it so much, I was so disappointed with the ratings! 

Beautiful mind

My love eundong

Argon

 Elif :

Que Sera, Sera

Age of Youth

Nine

Because This Is My First Life

I agree with you. Because this is my first life is a beautiful drama.

Depends on what you mean by underrated. For me it is Avengers Social Club and Chicago Typewriter. Both of these were great but didnt get enough attention here on MDL (despite having high score).   

Bring it on ghost is a good drama but rated only 8.3 on MDL

Chicago Typewriter

Tunnel

A Poem A Day

Naked Fireman

Ms Temper & Nam Jung Gi 

I wasn't really into it the first time but I watched it again recently and it's grown on me.

Heart to Heart and Beautiful Mind are two of my absolute favorites but you don't hear a lot of people talk about them.

I'm going to watch heart to heart

Scent Of a Woman is such a great romantic drama, with a strong female lead and a loving male character. Such a greach drama but really underrated.

A Love To Kill

Hotel King

Time Between Dog and Wolf
