This is a hard drama for me to rate, because on paper this should be my favorite drama EVER! It has so many elements that I love in a story, yet something falls short. Now that it's over, I am a little disappointed, but not because it's bad. I think I am disappointed because I feel like it should have been so much better! I will start with what I loved, which was the plot. The story is definitely one of the most original ones I've ever seen in a drama. It's creative. It's suspenseful. I never could anticipate what would happen next. In the beginning I was completely in awe! There was romance, mystery, action, and humor. I almost gave the story a perfect score, but there were too many minor holes, odd changes in direction, and confusing elements, that stopped me from doing that. There was also the fact that the drama started to lose it's charm as time went on, but I'm not convinced that was because of the plot. This story revolves around Kang Chul, and I think Lee Jong Suk did a good job of bringing that character to life (see what I did there?), but there was something lacking for me. He had the charm down, he's easy on the eyes, and the action scenes were pretty good too, but the emotional scenes were lacking. That didn't make me dislike his performance, it just made me not feel as emotionally invested as I should have been. I know it's a webtoon, but he went through a lot, A WHOLE LOT, and he seemed to be way too cool throughout. That sorta worked because he is literally playing a 2 dimensional character, so I forgive him. Who I can't forgive as much is his costar. Don't get me wrong, Han Hyo Joo is cute and likable as Yeon Joo. She looks great with the leading man, and the chemistry in their early scenes together are some of the highlights of the show. The problem is when the show goes from partial rom com to full on suspense thriller. Suddenly their romance goes from 1 to 1000, and the chemistry is replaced with overdramatic declarations of undying love. As cute as they were together, their romance doesn't make the most sense, and that's when her acting let me down. Every time she cried I felt nothing. Every time she was surprised I felt nothing. I felt a little bit of the longing when she missed him, but not that much. I liked the character, but I just couldn't connect to her emotions. I think this is why this drama failed to meet my expectations. I am a cry baby, and this story called for lots of tears, and I shed not a single one. It looked cool, and they looked cool together, but I wish I felt more emotionally tied to the characters. My favorite character was actually the writer Oh Sung Moo. I think his story was the most interesting part of the whole drama. He was complicated, he was interesting, and he came the closest to making me feel any emotions. Kim Eui Seong was excellent, and the stand out! The rest of the supporting characters were great, and there were no real weak links. I loved the assistant artist so much - he was a hilarious sidekick. I also liked the reoccurring jokes with Yeon Joo's boss. I can't say that the acting was bad at all, but I just wished the emotional scenes were more believable. It takes more than tears to make emotions seem real. The other thing about this show that impressed me were the visual effects. They were perfect when switching between the two worlds. Yes, it totally reminded me of the 80's music video "Take On Me", which is a classic, but I liked how seamless the cartoon world mixed with the real world - it was just the right amount of cheesy yet realistic. How about that soundtrack? Umm... I can't remember a single song or melody, and I literally just finished watching it. Would I watch it again? Sure. I wonder if a second viewing would make things clearer in certain parts. The suspense would be gone, but there are still enough entertaining parts to keep me engaged. Overall, I think the creativity involved alone would make me recommend this drama to anyone, even though I feel like it didn't reach it's full potential. I blame that more on the leads than the plot, which was ambitious, but I've seen plots that made much less sense, and yet they still had a stronger emotional impact on me because of the actors. From beginning to end I was very intrigued, and I think the ending was great, but part of me is recasting in my head... Song Joong Ki or Jung Il Woo as Kang Chul? Kim Seul Gi as Yeon Joo? This is why I'm torn. Part of me liked it a lot, and part of me wants a do-over! It's like I'm... torn between two worlds (See what I did there?) lol.
