So I put the spoiler tag. To make it short: The series is well done. From the very beginning it's obvious that this is really good. Good actors, good script, good dialogues, good production. Still it took me 2 episodes to get hooked, but then I was REALLY hooked. It got better and better - until the last two episodes which I didn't like at all. So my issues with the series: The character were not likable and the plot became strange at the end. Gyu-Ri was so sassy and cool, wasn't she? The girl messed up everything. If you think about it, the moment she got her hands on the Ji-soo's phone sh*t happened. All the blood that was shed was because of a new client she scouted. She didn't do it on purpose and it really looked like she was in love with Ji-soo and she later proved how far she was willing to go to save him, but still. The girl messed up EVERYTHING. I was constantly thinking *Just let the man do his business*. But the man became a wimp later on. The only character I was rooting for was Mr. Lee. And then he died. And then he didn't. And I'm not a fan of that kind of plot where a characters comes back just to die again. I liked Min Hee mostly because she was friends with Mr. Lee. But otherwise she was not very likable either. The main character had a very questionable personality to begin with. I mean, if you do that kind of business you sure are shady! But he proved that he was willing to risk his life to save Min Hee (he tried to hold back the bad guys so she and Mr. Lee could escape), just to let her die an episode later. It just made no sense. I don't know if you can call that "character development" or bad writing. The end felt strange to me. Like it was the end of a season and not the end of a series. I enjoy an open end if it's well done, but here it makes no sense. We don't know if Min Hee will live, die or survive with brain damage, we don't know if Ji-soo survived or not, we don't even know if Mr. Lee survived. The police officer never said clearly that he was dead. Everything was resolved more or less, but we don't know what happened to the characters. That was left completely open. So yeah, objectively speaking this series was very well done, very suspenseful (I had to hold my breath several times and binge-watched it in 2 days), but subjectively speaking I don't like the end, I don't like the characters, and I was in general very disappointed. So I'm conflicted about the rating. It's too good to rate it lower than 9, but I wished for a different end. I wished for the main character to die, honestly. I didn't hate him, but I thought his death would have been a better closure. I saw rumors about a season 2, so the end would make more sense considering there will be a continuation. Still I wonder how this season will look like. Ji-soo and Gyu-Ri have to flee, leave the country maybe, will we see new characters and a completely new story? Nothing is confirmed at this point, so well, whatever.
