Hi all

I need a drama with good editing and direction.While watching,it should be like a film experience.There are some well directed one's but the editing pace and speed is very slow.I want well edited with very good shot cutting and speed.It should not look as slow.

Mr. Sunshine (Historical,  Action, Romance, Drama, little Comedy here and there) fits the bill. Cinematography, music, art directing, acting etc. are all very well done and top notch. So well done that it will leave a deep hole in your heart after you've finished it.. 

Maybe Arthdal Chronicles  (Fantasy, Action, Drama, etc.) which will make you feel like watching an old Conan the Barbarian or Red Sonja Movie xD 

Maybe Kingdom Season  1-2 (Historical, Horror, Action) which is a drama around a Zombie outbreak during Joseon Era. This Show even got widely accepted by people that don't watch asian dramas usually. And Season 2 finale was just sick, haha.  Higly recommended if you enjoy the Zombie Movie Genre.

100-manen no Onna-tachi (2017)
An example of contemporary Japanese cinema just in series format. 

Burning Ice (2017)
The series production heavily reminds me of the work of Diao Yi'nan who specializes in Chinese Neo Noir through a auteur perspective.

Nowhere Man (2019)
If you're familiar with the Second New Wave movement of Taiwanese film you'll definitely adore the cinematography within this series. 

Light on Series: The Bad Kids (2020)
A show somewhat remenicist of the 6th generation of Chinese arthouse.

I'll also leave Followers (2020), and Danger of Her (2020) as other recommendations. I also believe that networks like WOWOW (Japan), and OCN (Korea) produce quality content. You just have to read through each show's summary because at times the production may be good, but the storyline may lack.
