The one thing that I really did like about this drama was the premise: two babies switched at birth, growing up in their enemy's family, and then the resulting crisis years later. It seemed like a compelling story, but unfortunately most everything else about this drama kind of ruined it for me. The drama was way longer than it needed to be, first of all. It would have been a better drama if they'd cut the number of episodes in half. Often the story went around in circles, with no real plot development happening. You get sick of seeing the characters doing and saying the same things for the umpteenth time. It got incredibly boring to watch after a while. As the story clunked along, it increasingly became awkward and lopsided. I found it difficult to really believe or understand the motivations for the actions some of the characters were taking, since they often seemed inconsistent with the character. One of the main actresses apparently bailed before the end, and her character gets an awkward sending off, leaving a very obvious void for the remainder of the drama. At times scenes were overacted to the point of just seeming ridiculous. Exhibit A: when you're emotional and talking to your brother, you simply yell each other's names back and forth for no apparent reason. "Hyung!" "Dong-wook-ah!" "HYUNG!" "DONG-WOOK-AH!" "HYUUUUUNG!" "DONG-WOOK-AAAAAH!" (rinse and repeat). Likewise, when you get angry with someone, you're supposed to yell their name angrily and then silently stand there, staring intensely at them. If you watch this drama, you'll notice the precise same intonation every time someone says Shin Tae-Hwan's name: "shin Tae HWAN!" Despite the overacted scenes, I don't think most of the actors were outright horrible (when they weren't yelling someone's name, at least). With one exception, that being the White Guy. White Guy could not act his way out of a paper bag. By the time I reached the last episode, I was thoroughly sick of the drama and had lost any empathy I'd previously felt toward the characters. So the bad news: it's not the happiest ending in the world. The good news: if you're like me, by episode 56 you wouldn't care if all the characters took a flying leap off a cliff.
