Overall a great series to watch, not boring at all very well paced.
Only for those brave enough to see a lot of bloods here and there.
Great acting for all the actors and actresses
Great actions & fighting scene, looks like real. Yes even though sometimes it's just a bit doesn't make sense (example on the last scene when Ji Woo stabbed so much yet she survived and managed to kill Mujin). Yes we all know the bad guy must die.
Interesting story, even though I already managed to guess what is Ji Woo father in episode 3.
Great directing, lighting and visual. Blood looks real, some movie the blood like tomato sauce and just too much, but here it looks realistic. Thumbs up to the director and production staffs.
Overall even though there's flaws , this is a good series.
Looking forward for season 2
