For me this show is great from the action scene, acting of all actors and lastly production but...
There something unclear..

The POWER SYSTEM---

- How will you determine your own strength if someone has same ability as you??

-How will you determine your chances to defeat your enemy if he has same ability as you?

I DONT WANT TO GET AN REASON LIKE

" Because they are main character, they need to win."

Poor writing character for the villain ( Not for north koreans but for NSI chief and tracker old man)

They are EASY KILL..

Conclusion:

I love this show but those question, dont give good reason to rate it higher.
