This beautiful story has so many unexpected twists and turns to keep the viewer engaged! Hyun Bin and Son Ye-jin are perfect in their roles! They are accompanied by a stellar supporting cast. You also can't help but love the villains because the acting is just outstanding, even among the children. True, there are some depictions of N. Korea that are inaccurate (bright clothing, for example), but overall there was so much research and thought put into this drama. I have watched it three times and recommended it 300 times! You will not be disappointed, but you will laugh, you will cry, you will sit on the edge of your seat! Great for men and women to watch, or watch together. Not my utopian ending....I would have done a couple of things differently, but I'm in love with this drama and every actor.
