it all 5 stars until the beginning of episode 7. It feels like story / creative directional changes in the middle of shooting. The intensity that build up from episode 1-6 just went away.
Some missing point that could made it perfect show :
1. Hyun-Ju was core part of the group, but never going back again for the remaining 2 EP. Instead they introduce new character.
2. Never hiring any mercenearies despite unlimited money. Some may argue for the sake of dramatization. But it fails logically. When your lives at stake but not hiring some bodyguard to backing you up just miserable
