I think the best thing in this drama is the main plot. It was interesting for me and each episode made me even more interested in what was happening. Some things were a little forced but I understand that it happens for the drama to move on. I also liked the scenery and some unpopular opinion but I didn’t find the CGI a big problem, it was ok for me.

The thing I didn’t like that much was the characters, most of them weren’t that interesting (I guess the best of them was Bae Doona’s character and maybe the doctor). I was a little disappointed in Gong Yoo’s character because ok HE’S HOT but being the leader of the team I expected him to be more charismatic idk. I liked him more later tho but still, didn’t love. Lee Joon’s character seemed lost in the beginning but he grows up in the story. I didn’t love him either but he was pretty good in the role. The others characters weren’t that interesting for me or were annoying. I think that a drama with 8 episodes (45/50 min each one) was too little to develop that much of characters.

Still, I recommend this one if u want something different from usual kdramas and if u are looking for something short and interesting to watch. It’s an immersive drama :)
