What the f*ck.?
That's the only thing that comes to mind after finishing this series just minutes ago.

I had really high hopes for this series since I seemed to enjoy the first half of it a lot but towards the end, it just got worse and worse. The story was doing good but then it just made a gigantic 360. I have so many questions like why did they kill literally every single main and side character?? why was Hwang Daedu so overpowered?? Just what?? I usually don't leave bad reviews but I was so disappointed, it feels like they just replaced all of the writers near the end.
The end makes me feel like I wasted my time watching this. Now I look back at some scenes and they feel really useless. It makes me sad because I really liked the characters and story but they ruined it, aaah it had so much potential T.T

I'm still giving the acting an 8.5 because they were really good actors in this series but overall I do not recommend watching this. Even if you like darker themes, it just feels like a waste of time.
