From start to finish, the show was incredibly well pieced together. The main setting at them goshiwon really captured the creepy feeling of someone watching you at every moment. From Lee Dongwook creepily staring through a small hole in the wall to the camera panning over / through walls, you felt like another person peeping into hell. At certain points you pitied the characters, regardless of their "morals" (which it seemed every character was twisted). Some parts of the show are confusing leaving me with unanswered questions, but doesn't that just add to the suspense? The last episode is a long and bumpy ride leaving me wide-eyed and honestly begging for a season 2!

Overall, it's a binge-worthy show that will leave you feeling all sorts of different emotions. Dramas like this are a big harder to come by specifically because of how swift-paced the show is. No long and boring introduction to the plot, no gaps between conflict, and nothing unnecessary to the plot. Even the soundtrack was very good!
