My very first kdrama and Asian drama that i watched back in 2013, but it's also one of my least favorite live action versions of the original story (manga)
I haven't watched the original version, but I liked this one anyway. It wasn't that good, but it wasn't that bad either. Somehow Berlin is my favorite even though he's like the worse one.
I've added all actors that they mentioned in their end credits, but sadly I couldn't find the name of the actress who plays Eun Ji, didn't find any results when I searched around in Korean/Hangul
It took me 4 months for me to finish this kdrama, my least favorite apocalypse plot so far. Also Nam On Jo was a very annoying and useless female lead, I just can't stand characters like her. Also there was no character I felt any sympathy for, so it didn't matter to me if they all survived or died. The story itself was very repeating with the same stuff over and over again, so the "thrilling scenes" didn't make me any more excited to continue watch it, it felt like something in the plot was missing to make it interesting. I rated it 6.5/10 on MDL and 6/10 in IMDb.
I'm very skeptical about S2 because they've to do an own story as the original story (manhwa) is finished and there's not so much left to take from it. If it's true that the character/characters survived in Netflix version that is/are dead in the original, I then feel like it has lost the story itself. I'm not a big fan of when they change big stuff like that. Hopefully they'll not ruin it and end up good.
