For the first 1/3, the drama was nauseating and almost unbearable at times. They were Jumping between too many characters in a single episode every episode and there were too many short quick cut scenes in a single episode. Doing so doesn't allow the viewer to have a breather or to get to familiarize with the characters. The problem solved itself for 10 episodes or so then returned to the same editing style and kept switching between both styles until the end.

Usually for family drama there is one major story that you see it develop till the end but not in this drama, there's no major story only a collection of side stories some end and start at different times. The synopsis may allude you to believe it's about the "meaning" of family, although it's true to some extent, but that was hardly given any focus or attention. The individual stories of the younger generation took the biggest cut. There a far more superior family drama that tackle the multiple generation dynamic much better.

Not a single story of these younger generation were interesting, all were underdeveloped, they either started too late or ended too soon or both. Se Hee and Na Yeong stories had potential but they never gone anywhere and concluded too early, they deserved a better writing. The female cast in general was strong but male counterparts were generally weak. One more thing, why did they had to bring the mood down with that ending?
