I decided to watch this just 5 days ago and was able to blast through the episodes in the shortest time possible. The main plot was okay. I disliked the fact that they used one-dimensional evil characters to drive certain parts of the story. I also didn't like the laundry list of rules angels supposedly follow in this world, but I did enjoy how the film delves into the philosophy of the existence of evil and the existence of an omniscient and benevolent deity. The film assumes a world where God and angels definitely exists, but also asks poignant questions that people ask all the time in the real world.

As for the performances were good but one of the reasons why I even began thinking about writing a review here was because I especially gravitated towards Shin Hye Sun's portrayal of Lee Yeon Seo, the distressed, handicapped but eternally grumpy ballerina who has all the power but living through a world that clearly no longer wants her - including her extended family. I first saw Shin Hye Sun as Woo Seo Ri in Thirty But Seventeen and already noticed her undeniable charisma, but she was EXCEPTIONALLY MESMERIZING as Lee Yeon Seo. She literally carried the whole series and stole every scene she's in.

On the other hand, L as Kim Dan felt like he was playing a side character for the 1st half of the series - almost as if his sole purpose was for comic relief. His was almost child-like next to Hye Sun's performance, but he did show some promise in the later episodes. He also looked a lot younger than Hye Sun, so that didn't help to establish him as the male lead next to Hye Sun's stoic and electrifying Lee Yeon Seo.

If you hate the fantasy plot or any other aspect, I'd still recommend this drama solely for Hye Sun's performance. She will hypnotize you. She will make you mad. She will make you sympathetic. And she will make you an overnight fan. After this, she has become my #1 Korean actress when it comes to acting chops and now I'm eagerly anticipating her next project.
