Top 3 Favourite K-Dramas?

Healer, City Hunter, IRIS - 100/100

They're great fast-paced action on high budget that has both romance and thriller elements. The cast was perfect and the storyline always gets better in all of them.

Kill me heal me

I hear your voice

Pinocchio 

If I could only choose three.....

Reply 1997 : the one that feels like home. the characters and plots, despite any silly elements or happenings, are embedded in me, at this point. its importance is often overlooked; people forget that this was the cable drama that birthed not only the reply series, but tvn as a network.

Coffee Prince : the one that pushed the limits on people and relationships. the alien speech will remain as one of the most romantic moments probably ever. the beach remains one of the most tension-filled scenes i've ever seen on screen from any form of television.

Sandglass : the one that used a burned out match to light a fire. deeply moving and ever-relevant, the careers it sparked ever-present. it leaves you to wonder if there'll ever be another that had an impact anywhere as similar.

Cheese in the trap

I'm glad someone else liked "Cheese" as much as I did! I seem to only read negative comments about it. 

There is a serious Lack of "Goblin" in this thread. It should not be getting less top 3 mentions than Scarlet Heart Moon Lovers IMO.

Anyways 

1. Goblin

2. You who came from the stars

3. Legend of The blue sea. 

1. Scarlet Heart: Ryeo
2. Goblin

And for 3, I can't really choose 3 K-Dramas that I love, But the show, One More Time, is probably a close 3rd. I rate them all 10 because they have changed my life.

This is my top 3:

1) King2Hearts: The plot is unique at best and i like the pairing couple in this drama.  The political aspects, the dialogue with small and middle nations against bigger corporations and other stuff makes me rewatch as soon i have time. 

2) The Master's Sun: One of i most loved. We have several epic scenes about our OTP that made me cry at some moments. One of the best of Fantasy/supernatural genre and was a rollercoaster of emotions.

3)Fugitive: Plan B: My first K-Drama. I never laughed in a K-drama as i laughed here. Rain was superb and the chemistry was good and off the charts. I begin to love action comedy because of this drama
