Yeah, but Pandora is kind of special in that it's all about the visuals. Most IP lands don't have that.
If you have no connection to the IP and it's not something visually spectacular (like Pandora), the land itself may not do much for people. Star Wars is big enough that most people have at least seen it, but if you hadn't and had no interest, I don't think Galaxy's Edge would be especially interesting overall. That's likely true of Hogsmeade too -- Diagon Alley has a bit more going for it with the dragon etc., but HP is in the same category as Star Wars in terms of being a mega IP. Something like How To Train Your Dragon isn't remotely in that category.
Of course the attractions matter the most, but if you're going to spend a ton of money on theming shops etc. and people just don't care about them, then it's probably not the best investment.
