What's the best Korean drama you've ever watched and why?

Okay I want you to review all the netflix kdramas from now on because your descriptions make me understand much better if I'm likely to enjoy it. Thank you for the detailed response!
Have you seen Mystic pop up bar? Or tomorrow? Both are about the after life. Mystic pop up bar is more fun and lighthearted, any romance is very much a B or even C plot.
Tomorrow definitely delves into societal problems and Japanese history more because it's about souls trying to stop suicides. No romance.
Sci-fi is a genre of K-drama I’ve never engaged with, but your description of “Sisyphus” has me intrigued! I’ll have to check it out next time I’m on Netflix.
- Sisyphus is really great. You should also check out Alice (not to be confused with Alice in Borderlands) on Netflix. It's also a time travel series but its true strength comes from its characters and all the different story threads coming together (which reminded me of the first season of Heroes).

I mean... does Squid Game count? 'cuz it's fucking based.

I haven't seen it yet! Was it actually good or just trendy?
- The trend was safely justified
- Really good
- It's amazing. Very worth watching!
- Just trendy. Alice in Borderland (Japanese) was a million times better with a similar story but somehow less hype.
- Worth watching, but only watch in English if you think you can get over the dubious dub. After a few episodes it mostly stops bothering you, but it's probably better to watch in Korean with subtitles if you're sensitive to that.
- I started watching it because I wanted to see what the hype was about, but I was instantly impressed by just how good it was. The writing, acting, direction and themes are consistently strong, and while the ending was a little strange, it's overall phenomenal.

Crash Landing on You (2019) has like every single romantic comedy trope and it was still fun. Kingdom (2019) was also good. It was a fresh take on zombies and suspenseful, but season 2 left on a cliffhanger and season 3 is in limbo.

edit: I forgot Mad for Each Other (2021)! Another mostly romantic comedy about a guy with anger issues and woman with paranoid delusions as neighbors. It's quirky and quick paced. (tho TW for past domestic abuse.)

Not a lot but the wife and I enjoyed Attorney Wu and Alchemy of Souls. Simple storyline and sometimes unpredictable.

Extraordinary Attorney Woo is easily the best I've seen. I actually felt like a better person for having watched it. The themes are powerful.
Alchemy of Souls had amazing visuals. Thats what caught my attention. It turned out really good though
Alchemy of Souls has such a good soundtrack!

The Glory really had me hooked the whole way.

Agreed!! Too good !
The ending chef's kiss 💋
I had to scroll way too far to find this. I loved this show and can't wait for more.

City Hunter is awesome.

What’s Wrong with Secretary Kim is probably my fave.

Witch’s Love is so cute ☺️

Descendants of The Sun still have a special place in my heart. Had a great soundtrack, and the chemistry was just fine wine.

Train to Busan

It's the only Korean movie I've watched. I guess it's technically a zombie/horror movie but I would argue that it's still pretty dramatic and should count as a drama.

Also, it's a solid movie. Would recommend.

Reply 1988. It’s on Netflix.

Can you explain what you liked about it or what makes it good?
- I think I can relate to it personally. I am from that part of the world.

The Man From Nowhere gets my vote.

Parasite, Train to Busan, and classic Oldboy are other great ones off the top of my head

Everything that Bong Joon Ho has ever made. I've recently watched Mother (2009) and Memories of Murder (2003) and after watching these, including Parasite, I've got to say he is one of my favorite directors. He is just amazing.

Also I've got to say that some of my favorite movies are korean movies. They got some amazing horror movies like I Saw The Devil. I'm going to continue watching them as they are amazing at what they do.

Oh my ghost. Great drama.

Pachinko was really good. Kingdom is awesome too.

The Glory

I haven’t watched many but I really enjoyed Kkondae Intern. Also the Korean version of Designated Survivor which I think was better than the US.

Juvenile Justice was really great, but it's hard to say why without getting into spoiler territory. Let's just put it down to overall character development.
