Honestly, while watching the first half of this drama, I was so sure I was going to give this drama a perfect 10. However, I guess that's where it all falls flat. While the second half is by no means horrible, it just doesn't live up to the expectations set by the first half of the series. Not that I didn't enjoy it. It's just that it set up so many questions that weren't answered. Still, this is one of my favorite dramas that I've ever watched. The premise is great and I haven't been so excited to watch a drama weekly like this one. I love the idea of two worlds and I love it was handled in a way that didn't make it seem cheesy at all. The relationship between Kang Chul and Yeon Joo was perfect and even the side characters were adorable most of the time. Plus, the father had such interesting moments, and my heart ached for him because I couldn't even begin to imagine how it must be to be him. Sadly, this drama does lack resolution on some things. That's the only way I can say it without spoiling, but there were a number of fundamental questions that needed answering. That was one of my biggest qualms. I needed to understand this drama more than it let me. It felt dragged on at the end, but no questions were being answered. Why, writers, why!? The cast was GREAT. I loved the acting, and I can't even imagine a different cast for this show. Even Crazy Dog was perfectly casted and I'm happy. I'm looking forward for more dramas with these actors. And the music, although repetitive at times, was used well, so I have no problems with that. I would probably rewatch this in a year or two, but I'm not sure how the experience would be since half the experience is the thrill of not knowing the ending. Although the cuteness of it all might make it worth it. Still a worth watch and definitely an amazing drama.
