What I like about the series is that it's not really a sports movie, as you might conclude from the title. It's more like a nice blend of supernatural, detective, and romantic elements woven into a sports movie plot. There's a mysterious undercover villain that adds an intriguing layer to the story. The characters are well-developed and psychologically complex, making plot twists less predictable, which I appreciate.
I've never been a fan of sports movies, but I really enjoyed this one. The original soundtrack is also quite good; I've listened to it many times.
But now, let me tell you about the things I don't like about the series. The final episode is really a mess. The actions of both the villain and the hero lack logic. A small, insignificant slip provokes the cool-headed villain into self-destructive, suicidal actions. Meanwhile, the hero accepts his lover's dubious actions without question. There should have been a stronger foundation for defeating the villain and at least two episodes dedicated to the lovers' journey back to normal.
