One of the most phenomenal dramas ever. 54 episodes is a ton, and it does suffer from some pacing issues (as anything epic of this length must). That said, I couldn't seem to skip more than a minute of this drama! Every character is compelling, each episode's plot is worth watching...I got to episode 25 and somehow after that couldn't manage to stop watching! This has got to have some of the most satisfactory conclusions to plot strands ever. Believable acting, heartbreaking stories, you'll want to cry your eyes out in happiness.
