Probably one of the beat TV shows I've watched in my.life. I don't remember a show where it's got me crying at almost every episode. If I'm not crying then I'm laughing or smiling. It's normally all 3 per episode.
The characters are thoughtfully and carefully built and when there are certain movements that would feel cheesy otherwise but it doesn't because those moments are earned. This is the mistake a lot of shows make. They rush development of story and character and drop big moments for the shock or drama without those things earned.
The magical elements are another special thing. And I love the concept of a hotel for ghosts. The magical supernatural elements give the show another layer that makes it special.
I think I'll never forget the charters or the story. Definitely 5 star for me.
