Now I understand all the hype towards this show...having read a lot of negative things I was reluctant to start this thinking what if it turns out like one of those shows that is loved by the masses but is actually lame...fortunately that was not the case..though far from perfect, the show is extremely entertaining thanks to its brilliant production values, the wonderful OST and the overall great performances ( though not all of them were that good )...the biggest strength of the show comes from its highly likeable characters whom you can easily root for...all the 4 leads have done an incredible job ( though I find Song Hye Kyo a bit stiff in some scenes ) in making the characters so relatable that you can't help crying and laughing along with the them...the biggest flaw of the show is its uneven pace and writing...there were episodes were so much was packed in just one while there were a few where hardly anything happened ..but these are just minor nitpicks in an otherwise engaging and satisfying drama...if you are hesitant about this one like me, please don't be and give this one a try..ul end up liking it if not loving it!!!
