"When Duty Calls" had everything to be an almost "Descendants of the Sun" Chinese version, however the lack of action and military scenes spoiled the context of the drama, for those who watched it saw that the first episodes were fantastic but as the plot uncoiled loses focus and brilliance, down literally downhill, story barely told is the problem, the director did not know how to give creativity to maintain the level of satisfaction required, the novels are weak, the cast though jovial and acting could do nothing with a poorly written script. The soundtrack until it is very good, the narrative was lost and in the end it was a disastrous drama for lack of planning.
