Well if you believe the hype this show is supposed to be as good, if not better than GOT. I think those who wrote those reviews were either paid reviewers or patriotic Koreans.
The story line was interesting and novel but predictable. The English dubbing was atrocious, very spaghetti western. I preferred to read the subtitles than listen to the dubbing which lacked authenticity.
I’m unsure whether it was intentional or just how Korean people are but I found it had a racial undertone of Korean superiority to the Pakistani character.
Overall I found it over rated and had I not invested the time watching the first few episodes and believed the hype I could have easily given the remainder of the episodes a miss, however now I’ll be watching the next series (subtitles only) to see where it heads.
