I’ve said this before and I’m sure it annoys a few of you, but other than Nintendo I don’t think any of the other current rumored worlds are from very popular IPs. Fantastic Beasts is no Potter, dreamworks franchises are no Pixar, and classic monsters are not Stranger Things, or A Jordan Peele or Remade Stephen King type horror that is popular now.
I actually agree that a classic/nostalgia land with Back to the future/jaws; and maybe some other 80s property sounds much more exciting to me then classic monsters.
Of course if the rides are great, then it won’t make much difference. It’s also possible I’m just showing my age, because I have no attachment to any of this stuff...except maybe classic monsters which I feel is probably the least popular idea for a land on here.
