I was a tad concerned after the first episode, that this was going to be another Netflix bait-and-switch. You know, the shows where the poster looks cute, and the trailer looks inspiring, but the show has dark and gloomy overtones. Even though it is early (2 episodes), I am glad to say that this isn't the case with this episode. Heart-warming, well paced, some mystery, and a really touching scene (or scenes) at the end. Sure, there are a couple of nit-picks. Like how a girl stranded on an island for 15 years and found alive wouldn't INSTANTLY be on every national news channel for weeks. So, the plot revolves a tad around her remaining unknown. Again, a tad far-fetched, but excusable if it pays off going forward.
And though I am not one to vote high or low based on an actor or actress (in fact many of my reviews make fun of people who obviously upvote atrocious shows because they're blatant fangirls or fanboys), I have to say, at this stage in my Korean Show watching, if it has Park Eu-Bin in it, chances are, it is getting a high rating. She is THAT GOOD! Amazing actress.
