Jenipeo:

If you mean the episodes were long:

2. A Korean Odyssey - 20 80-minute episodes

3. Goblin - 16 82-minute episodes

4. Mr. Queen - 20 80-minute episodes

i meant the quality, style, atmosphere...

6. Hospital Playlist - especially season two where some episodes were almost 2 hours

If you’re looking for the quality, then it’s #2?

2. Longest Day in Chang’An 

3. Luoyang 

But if it’s continuing from the previous entries, then these are numbers 8 and 9.

10. Kleun Cheewit  has 15 episodes (1 hr. 50 min per episode, there were so many side stories)

If this is #10, someone can pick the next topic

I guess you're on 5?

6. Kingdom 

7. Girl from Nowhere

8. I Told Sunset About You (duration and the story and cinematography all made me feel like I was watching a movie.)

9. Vincenzo

10. The Sound of Magic
