This drama would've been heaps better had they focused on Man Wol's story. It was compelling and got me interested in the drama. But they didn't spend as much time as I would've liked. I'm okay with the backstory of the other ghosts in the hotel, they were cool and I liked them enough. But I spent a lot of my time just wondering when they'll get back to addressing Man Wol's origin.

I also didn't feel attached to the male lead. It's not a slight to Yeo Jin Goo at all, but he didn't have any chemistry with IU, at least in my eyes. I liked Lee Do Hyun better.

IU was awesome though, as usual. She's a fantastic actress.

Overall, will I rewatch this drama? Probably not. I haven't found myself wanting to, not even for a specific scene. It's not horrible, not bad, but not great. The emotional moments didn't hit as hard as I wanted them to, and I didn't get attached to a lot of the characters. I don't remember any standouts from the OST either, but it didn't annoy me.
