I have mixed views about this series. On the one hand: Hyun Bin! On the other hand: shitty writing. The Story: Waaaay too long. This could have been shrunk down to a 16-episode show and it would/should have been a better drama. Meaningless plot lines were dragged out, hypnosis was treated like some sort of super power, and I don't know but I'm pretty sure this writer didn't do much research on DID (I'm not saying I know more about DID than she does, but I'm pretty sure DID doesn't work like that). The whole kidnapping plot was something that was supposed to keep watchers on their toes, and although I think Sung Joon is brilliant, more could have been done. The Cast/Characters: I cannot even right now. Hyun Bin could have picked a much better drama for his comeback. I need to go rewatch Secret Garden right now. Seo Jin was a much better character than Robin, who seemed over-the-top and fake. I liked him when we first met him, but I began to want Seo-jin more. Hyun Bin can act, I'll give him that, and he may have salvaged the train wreck that was this drama. What even happened to Terry? The third personality barely had half an episode to himself before we never saw him again. I have no idea what Han Ji Min was doing, but Hana is the next Bella Swan. No expression, no personality, selfish in the name of selflessness... and practically no chemistry at all. I was rooting for Eun-chang and Woo-yong more than anybody else in the show. The only delight I got was in Cousin Seung-yeon and his weirdness. I do not recommend this drama, but if you like this kind of thing, then watch it if you like flat plot lines, poor writing, and Kristen Stewart-characters.
