I'm giving this a 10/10, because I loved watching this from beginning to end, perhaps with the exception of e13.
With that said objectively this is quite bad. We could give it an award for "the most cheesy lines ever", I mean really it's insane how bad the script is. I guess you could say that this is the ultimate guilty pleasure, because I know that it's bad and yet I couldn't hate it for a second. As a huge fan of Goblin I love Inna & Dong Wook, but their acting in TYH is the worst it has ever been. Inna is an amazing actress, she's been awesome in everything before, including variety TV, but I think this cheesy character was too far outside her comfort zone. Their chemistry wasn't nearly as good as in Goblin either, I don't know, it just felt off. Honestly I don't even understand myself why I liked this so much, I mean it's so cheesy at times that it causes physical pain. I guess the feeling is not entirely dissimilar, when I listen to that "We Built This City" cover that came on in Grey's Anatomy that one time. Perhaps I'm just shallow & I just enjoy everything my favorite idols appear in??? (this would be a first for me)
They had to drop the stalker ark prematurely, because of real events in Korea, but I did not mind really. I mean sure it's sad that they had to scrap the script from episode 13 onward, but it might have turned out more entertaining this way. I imagine that originally the second lead couple was meant to fight alongside JungRok vs. the stalker guy and that was the whole point of their story, to make the legal proceedings more interesting and fun in the last episodes, but I think the melodrama all of this meant to cause could have ruined the show for me, I don't know. I liked the ending a lot, the last episode was especially nice, despite the heavy product placements. (eating Subway sandwiches, while charging a Samsung phone with yet another Samsung phone!)
