My take on this drama may differ from most. I really enjoyed it and don't understand why it received such a low rating. It blends sci-fi, medical themes, adventure, and memorable characters, along with a great mix of history and fantasy. It's a well-written and enjoyable drama that deserves a higher rating. While it may not be a masterpiece, it fulfills its purpose of being enjoyable and creative. Additionally, those criticizing Park Min Young's acting in this drama should get their eyes checked. This is clearly one of her best works, and her performance in the romantic scenes was exceptional. The entire cast's acting carried the show, even though I didn't particularly like Kim Kyung Tak's character or the actor's somewhat mediocre acting. Despite this, I stand by my opinion. The entire cast's stellar performances overshadow any shortcomings. Watching this drama is definitely worth it; you won't regret it at all.
