At the start, Legend of the Blue Sea seems to be like any other show where history repeats itself again. However, the amazing acting of the cast, especially the 2 leads, made up for it greatly. Towards the end the story started to get exciting and you wouldn't be able to pinpoint what they were going to do next. Definitely a must watch, but will probably not rewatch as the element of surprise and suspense would not be there anymore, and that was what kept the show going.
