I really, really wanted to love this show. The tone in the beginning was intriguing, the comedy/drama was well-balanced and fun, and the story was so engaging. But there was so much wasted potential. Shin's story was tragic and emotional, and I was deeply moved by his character, which is why I'm not rating lower. Yet the focus on the "fated" romance and the fact that it started when she was so young just bothered me. You can't tell me that these people were meant for each other just because they're fated; show me, let me feel their connection. I didn't, and that's where this fell flat for me.

Story: All over the place. Too many interweaving character storylines and relationships fighting for center stage, too many repeating scenes, and truly atrocious pacing. I couldn't stand how slowly this moved, honestly. It felt like it started out strongly, but then characters would spend episodes doing nothing. They would talk, they would be cute, they would be unsure, but nothing really happened for so. Many. Episodes. And then when something finally did happen that brought the characters into conflict, it was too quick to feel at all developed. In particular, an antagonist popped up later in the series and when they dealt with them, I was left thinking, "...that's it? That's how they're gonna do this?"

The characters were okay, but Eun Tak was just... not very well-developed, in my opinion. She's a bubbly, optimistic girl who can see ghosts and wants to help people. Okay, why? Why does she cling to Shin strongly at the beginning, and am I supposed to be charmed by the fact that an immature teenager is flirting with a 1,000 year old man? There wasn't much depth to her or their romance, and I felt disconnected from her character as a whole. Which further made the romance less engaging to me. Furthermore, so many of these characters had the potential to be amazing, with just a little more focus and development, which I think was sacrificed in order to fit so many of the other elements into the show.

Acting: I do like the cast, especially Gong Yoo. I was also incredibly impressed with Lee Dong Wook as I've thought he was a bad actor in the past, yet his work here definitely made me second guess my opinion of him. Kim Go Eun is a really good actress, yet seeing her play an immature teenager for so much of the show really grated on my nerves. But, boy, can she cry. Both she and Gong Yoo can make your heart ache, I'll give them that. Never been a huge fan of Yoo In Na, but she did well here, so I didn't mind her.

Music: Cute, fitting. I don't remember most of it, but I'm going to attribute that to the fact that I was consistently frustrated with the show. I can tell you that this is an OST that will definitely stay with the people who loved the show, though.

TL;DR: I'm glad that this show has brought such joy to so many people, but it disappointed me. I should have known better considering how I've fared with Kim Eun Sook's other dramas, but I was hoping this one was different. However, if you like her other dramas and are a fan of fantasy, fated lovers, a little bit of sadness, a little bit of comedy, and a whole lot of romance, then definitely give this one a shot.
