Dramas that are 50 or more episodes have to be judged differently from shorter dramas. I like them because there;s more room for story development and character development, but they rarely take full advantage of this. So usually they fall into two categories - dreadful and not dreadful. this one was god but like so many deteriorated rapidly at the end, especially the bit about the hospitalized father and all that business. It would have been a stronger story of he'd just gotten hit by a bus years ago (where was the ubiquitous K-drama dump truck that takes out almost everyone in there stories: Just when we needed it!)

It's important to note that this was a drama trying to make a point, albeit very heavy handed at the end - you have to live for yourself, no matter what Korean family custom dictates. This seems obvious to Westerners, but it is still a new concept in Confucian societies. So I give it a pass - including the truly awful mother - and give it points for trying to make a sicial statement. Would I watch it again?
No way!
