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 Borderland) 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).
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.
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.)
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.
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.
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.
