Okay, I've just completed it and it's a let down (not as much as 'Big' that left me angry and murderous for days after its completion but still I'm disappointed with MOTA....it had so much potential *sigh*)...I loved the first part of this drama: innovative concept and suspenseful but it all went down the drain in the second half...don't want to spoil it for everyone so I will just add/say that this drama is only watchable for Hyun Bin's fine performance (he's the heart and soul of this drama-the Pillar) and the stunning scenery (mostly Granada).
Dropped this at Episode 12...Yeong Jae wasn't cut out to be in a relationship in the first place. She is fickle and listless. First break up, I understood her circumstances (still Jun Young deserved some explanation) but second time around, it's hard to side with her...still I wanted to give the drama a chance because I thought that the third time would be the charm like the title implied...but no they decided to assassinate her character by making her more and more pitiful. At this moment, it was the point of no return. Jun Young should have moved on and Yeong Jae sought help. Thankfully, they didn't end up together (that's the only saving grace of this show)
