I've been seeing too many bad reviews on "Abyss" honestly for me i enjoyed this show alot. Watched it 7 or 8 months ago and the storyline was interesting. Its about a marble that can revive people back from the dead. The murder, mystery everything just blended in fine. The actors did a good job here too. I was totally hooked till the last 10 mins of this show. The ending was bad and had alot of questions unanswered but honestly if i compare how much i enjoyed this show till episode 16 to the last 10 messy mins then it was actually worth it. I would ask you to gice this show a shot. The first 2 episodes maybe a bit unclear but you'll understand the whole plot from episode 3. I didn't want to make this review too long because I'm scared i might give major spoilers. Plus i don't want to ruin anyone's experience of this kdrama. Watch it for yourself and see how interesting it actually is.
