Episode 1 is the best. The rest? Not so much. The actress who portrayed the character Seo-Hae is not effective! She was supposed to be a woman from the future with no food, no clean water, Radioactive environment but the director and actress didn't gave justice to the character.. She has a soft, shiny, and well-maintained hair..all she did was comb and fix her hair with her fingers even during the fight and gun scenes..
