The headline makes it sound worse than it is. The cinematography is great and decent acting from two promising young actors in Park Ju-Hyun and Chae Jong-Hyeop. Other than that, the rest is questionable. The series starts well with the introduction of the characters with Taeyong's and Taejuns' backstories. After that, it spends most of the time on pure negativity that it's become frustrating. Frustrating is neither entertaining nor educational. Fine, there should be frustrating characters and scenes but shouldn't take up the bulk of the show. Firstly, the more senior athlete agrees to drink and go snowboarding while drunk. Bad move for a senior and she has the nerve to bear hatred. Secondly, a parent puts her daughter on a towering pedestal that she can't see anything else below that. Is that really a way for a parent to behave? Writers and producers have great power to influence viewers and with great power comes... you know the rest. The issue between Taeyang and Junyoung could've been wrapped up in one or two episodes. At least then, the story could've been explored more from what goes on in episode 16. Furthermore, that love story formula of going out, breaking up and getting back together again is starting to err on the side of yawning. This could've been a great show had it followed the story of the manga novels or at least something very close to it. This probably sounds more like a rant than a review but I loathe to see a good show go to waste.
As a side note, professional athletes will usually have nutritionists looking after what they eat and drink and the amount of alcohol consumed shown is a hard No. The story is grounded in reality so it should at least be as close to reality as possible.
