Story - Looking back and reflecting on the entire story, I think it was quite interesting. It had intriguing surprises that kept the story quite alive. I do think 20 episodes was a bit too long though. I think they could have easily compressed it all into 16 episodes because right around the 10-14 episode range the story felt like it was really beginning to drag and I just wanted more reveals than I was getting. The revenge and romance definitely seemed to be the key points in the drama but, as for the revenge it really didn't feel like it was getting anywhere till the last few episodes when warnings finally became actions, and as for the romance I thought the main couple was cute in the beginning but after the second time skip I found myself barely interested in them at all. The only relationship I found compelling was the Sumi/Jangil love/hate relationship. But even their relationship at times couldn't keep my interest. For me the highlight of the show was probably neither the revenge nor the romance but rather to parallels and storylines that crossed and tangled between the two generations. How Seon U became so much like his father, Jangil like his, and Sumi like hers was what really kept be going in this story. There were so many layers involved in all of their relationships. Acting/Casting - I loved the whole cast. I felt they played out their characters quite nicely (especially LJH, he did an outstanding job) and for once I was quite amazed at how the older versions actually really resembled the younger versions (something that bothers me in so many other dramas when I can't connect the two ages because they look so different). My only complaint might have been that UTW did look way older than LJH which threw me off a bit at times when I had to remind myself that they are supposed to be the same age. Music - Ha. Well. Music. Right. It was okay I guess. The first episode was nothing more than a disaster but as the show progressed it did get better and better. Still by the end, I wasn't yet convinced I was digging the music and the music queues. Rewatch Value - Honestly, I don't think I'll ever have the desire to rewatch this from start to finish. It was interesting one time around because of the twists but honestly now that I know everything it just won't be that appealing again. I'll probably find the pace way too slow. I might go back and rewatch certain scenes that I liked (which will probably be in the first three episodes because they those episodes were honestly among my favorite...) but I'll probably never rewatch from start to finish. Overall - 7/10. It had it's flaws, quite a few of them, but the plot and cast saved this drama from becoming unbearable. Although it felt slow at times, it was a compelling story but not one I would watch again.
