Throughout the series it didn't really lag. the story moved forward through the phases and covered the story arc pretty well. I didn't care much for the Do-Sik storyline it felt out of place and irrelevant to the overall big picture his place would of beeen good without his "family history".

As the series wraps up it's great how they give each character a fitting end to their part.

With the finale having a satisfying ending.
