I heard Korean dramas are very popular all over south east Asia and especially in China. I'm starting to see why, as all k-dramas I have watched were great (move to heaven, squid game, my name).
The characters are shown very well and I could relate quickly. The cases made me think about law and justice. The pace is just right, the story thrilling and touching.
Sometimes I'm not sure whether something is Korean culture or individual character e.g. Bosses seem to yell a lot, and there is a strong hierarchy of respect between people, whereas in western culture everyone is more equal, irrespective of age and position (at least compared to as it's shown in juvenile justice). One case is about the education system where I also think some background info would be helpful to research upfront.
This left me a tiny bit confused at times.
9/10
PS: im not criticizing the show for showing Korean culture, just stating it may make some situations seem weird for westerners.
