I liked everybody in the cast except the FL Song Hye Kyo, I have watched several shows with her and just don't get the appeal. Her acting is flat and stiff and she never seems comfortable with any ML. (Which is especially weird considering she ended up marrying Song Joong Ki for a short bit. ) I never find myself empathizing with her characters, including her character in this series. I did not find it believable based on her behavior that the ML would try so hard to win her over, again and again.

The show would have been better off just focusing on the adventures of Yoo Shi-jin and Seo Dae-young and the medical team in Urk and leaving the main two romances out. As it is, I lost interest after the 239th break up of the ML and FL. The secondary couple was terrible. The secondary female lead was so selfish and immature in her decision making and so persistent that it just seemed as if Seo dated her just to shut her up. I never felt there was a chemistry between them no matter how many tears they forced out. Maybe the actor was just not good with romantic scenes?

Some positive notes, I loved how cheezy the American soldiers were, it made me laugh at how bad their acting is. I liked the fighting and action scenes. Watching shirtless soldiers jogging in formation is my new favorite pastime.
