You know whats missing: kids.
Kids are what drive fantasy theme parks.
Kids want to be Elsa or Luke or Harry Potter.
They drag their parents along.
And many times the parents remember their experiences as kids and it gives them warm fuzzies.
With respect to adult fantasy, none of those shows has the deep cultural hold Star Wars or Star Trek likely from kids watching these with their parents and wanting to be like Luke or Leia and Han.
Bridgerton might be good (or not) but it’s not family entertainment. Neither is Squid Game.
My guess is that most adults will consider these fantasy worlds either sad or just a curiosity and won’t have the same enthusiasm as Disney or Universal.
