Review frequently updated: EP1-7
The first few episodes guide us through the fictional world where the government has been involved in recruiting (might even creating, not revealed yet) superhumans as agents. From what we know the agents are retired and the story is now revolving around their kids. We see how their abilities have affected their lives and how their parents (former agents) are trying to protect them. The family and friends relationships are laid out pretty well initially. We are also introduced to what I can assume will be the main plot line, that the governments of different nations are trying to kill the former agents of South Korea. Why and how is not something we discover yet. From my understanding, the powers seem to be inherited genetically and the kids can have abilities of both parents, like our main lead Kim Bong Seok and the killer, a CIA operative (a native Korean who was sold as a child) has been tasked to take out all the former agents and their kids. The story is interesting and I cannot wait to see where it is taken from here.

Till now the storyline is fascinating and I enjoyed how the first few episodes were used to introduce us to the world and the characters. The series involves a lot of characters and their background stories which could have become messy and tedious if I had not binged watched it.

PS: If you are wondering, the VFx are amazing! Top quality! Very comparable to American shows!
