This well made and often gripping series shows in realistic detail an earthquake and it's aftermath in Seoul from the point of view of doctors in a hospital and the EMTs. The first part has well done disaster sequences in the first quarter. Then the deprivation of utilities and the difficulties of medical procedures is quite gripping. Some of the surgical procedures are quite exciting. I usually don't like the overly technical medical dramas but this one isn't boring since it's a blend of disaster and medical drama. They even manage to have some romance weaved into the story.
The cast is quite sympathetic and there is time to build up the characters and their relationships. Ki Young Kwang does a great job as the hero surgeon willing to take risks to save lives. Jung So Min is quite likeable as the sweet doctor from Busan. Ha Seok Jin is convincing as the more conservative doctor. His nurse love interest is played by the pretty and intelligent looking Yon Joo Hee.
The faults of this series don't spoil the whole. If this series had been shortened by a few hours it would have been much better. There are some repetitive scenes that should have been left out mostly about the evil doings of Director Park head of the hospital. He is just too insanely obsessed with getting our hero. Same thing over and over. The ending is satisfying.
Worth a watch.
