I think expectatives for Descendants of the Sun were incredibly high everywhere. I mean, it was going to serve as Song Joong-ki's comeback. And I believe it mostly worked very well. The story was alright. I usually love slice of life romances, so I had no real problem with the plot (unlike many people, who complain that the drama doesn't have a plot at all). The thing is that the story was VERY fun and entertaining, even if at many points it was too over the top. I must admit there were a few episodes that I felt were too unbelievable (especially episodes 11 and 12), but they were still fun. And well, the 'villain', was ridiculous. The cast was mostly brilliant. Song Joong-ki absolutely steals the show. He's extremely charismatic, and I 'm sure he could have chemistry even with a wall. Many people don't like Song Hye Kyo, but I think she did the best with what she was given. Jin Goo and Kim Ji Won (especially her) were great as the second lead, although I didn't found their story that interesting. From the supporting cast I must praise Seo Jeong Yeon and Lee Seung Jun, because their characters were one of my favorite things in this drama. On the other hand, I felt Onew was incredibly over the top, especially in the earthquake episodes. The soundtrack was brilliant. I'm used to watching mostly j-dramas, where there is only 1 insert song, or 2 at most. But here there were a lot, and I think I loved every single one. Another thing that must be pointed out are the production values. The show lookes GREAT, it really shows that it had a very big budget, and it even felt like a blockbuster at times. Like I said, the story is very fun and entertaining, so I'm pretty sure this has a fantastic rewatch value. To sum up, I think DOTS is a very entertaining drama, even if at times it's too over the top or unbelievable. And honestly, it's worth watching just for the cast and the production values.
