The weakest part of this movie are the characters. We are very quickly introduced to Makoto, a ghost that lives in the inn and constantly picks his nose. It's as off-putting as it sounds. He starts by harassing Okko and then badgering her into working as the junior innkeeper. Everyone else agrees to this, seemingly without considering whether this is what Okko actually wants or something that would be good for her. Makoto's character doesn't really ever improve, and he never takes responsibility for his poor behavior.
Okko herself has her own problems. She is your typical cliche shoujo heroine who is dim-witted and clumsy; she also constantly lets people walk over her and bends over backward to make the people around her happy. If this was confined to her job as junior innkeeper, it might have been acceptable, but it is an attitude that she brings to her entire personal life. She goes along with whatever the people around her want, whether it's her grandmother or a random ghost.
The rest of the characters are a random assortment of personalities. Some of them seem like they had potential, such as the fortune-teller who befriends Okko, but that potential was never met and the connection between the various side characters and the story is tenuous at best and awkwardly forced in at worst.
The animation was fairly lackluster. The backgrounds were largely fine and I didn't see any major problems there, but the characters were so oddly animated that they looked like the anime version of plastic dolls. The contrast between the backgrounds and the characters frequently made the characters feel out of place.
