I liked DOTS overall is it brought together military and medicine which are typically seen as polar opposites at the surface while in reality they share similar core values that save the common people. I felt that the main leads had a good connection in the beginning. They liked each other's personalities and went on a date without hesitating too much. The absence of the second main lead syndrome brought me huge relief. There were several inaccuracies and overdramatic scenes though. When Kang Mo Yeon and Yoo Si Jin fall from the cliff into the water, judging by the height of the fall, they couldn't have survived even if they fell into the water in a car with airbags. Also I wished that they showed the way Yoo Si Jin escaped from being locked up and returned to meet Kang Mo Yeon. It would have been much more interesting if they dedicated an episode to Seo Dae Young's and Yoo Si Jin's escape struggles. It felt like an originally intended sad ending was made happy to prevent backlash by fans. I believe that the end should have been better constructed to avoid this. I loved the way the earthquake brought together the military and doctors.
