Except ”our children” don’t care. Most parents aren’t plopping Timmy down with an iPad to watch MIB or Jaws. They’re not watching Mummy. Or Terminator. Or Back to the Future. They’re watching Trolls. They’re watching Transformers. They’re watching Fast and the Furious. Kids aren’t asking for Noisy Crickets and Neuralizers for Christmas; they’re asking for hot rods and magic wands.
Universal is keeping its parks relevant. People like to compare Disney and this regard, and you flat can’t. Magic Kingdom is based almost entirely on vanilla concepts, public domain stories, and cartoons. That gives everything they have an almost unending shelf life. Universal, conversely, is based entirely on live action films that have a shelf life of 15 to 25 years before it’s embarrassingly outdated (sometimes sooner).
And it’s such a mistake, Disney is starting to replace THEIR old, outdated stuff with... MORE MODERN IPS!
I completely get being upset that a favorite attraction is leaving. But it is inevitable. You might as well come to terms with it while you can.
