The idea is good although they didn't give enough details about the tyrant's project, Also the stories of some characters aren't really clear. The last episode was the best, but the first 3 episodes were a bit boring and not much happened in them.
Maybe if it was a full movie with a lot of details added,or a 10-episodes drama with details of the beginning of the tyrant's project+complete stories for each main character, it would be perfect
Because the idea of the drama is really great, but it was not developed well.
