As much as I enjoy that franchise I agree with you. For years I kept hearing ‘it’s better in the books’, I remember specifically people saying that about the organization that helps dobbie and his people. Fuggin, I read the books as an adult and it’s barely expanded on it at all, they just have more scenes about the organization but it isn’t ever truly relevant beyond explaining why Hermione does what she does as an adult.

It’s a charming little story that matured with readers and got a decent adaptation that led it to explode. Lots of luck to get to where it’s at.

I would love to see a wandering inn adaptation instead.
