Like many other medical dramas, Doctors is a mix of episodic cases and romance, but it ultimately falls a little flat.
The strength of the show is the acting. Kim Rae Won and Park Sin Hye both play their characters well enough, but it's really the supporting cast that manages to elevate the show, becoming entertaining and fun to watch. And all the little cameos sprinkled throughout also create memorable experiences in their limited screen time.
The weakness is that nothing ever really happens. The romance progresses slowly, gets settled and then cruises along with not much else. The larger arc of the hospital politics takes center stage at a point, but that story is mostly off screen action with plenty of talk and little doing. You come for the characters, not because of what's happening to them but because they're there.
A good watch for fans of the leads or those having a slow, dull stretch but the show doesn't have much else to offer.
