The biggest problem I have with all of this is that Disney knows how to create synergy, and they're really good at it and always have been. What happened with this?
They had the rights to Star Wars and a long timeline for building this while they were making new movies, cartoons, etc. How hard would it have been to just make Batuu a place in one of those movies to "make it real"? It should have been something where from the start they mapped out movie and land developed them simultaneously to create the synergy.
