Kind of defeats your point though because et is still an ip.
It’s a well done ride based off a classic ip that is still heavily regarded as one the top 10 best sci fi films in history.
Maybe the point you’re trying to make is the quality of the ip? Which I think is fair, but ultimately quality is subjective .
What I stated was "popular IP of the day" as in, what's hot
now whenever "now" is while they're deciding
.
Disney's flying Elephant ride was operating decades before Kang and Kodos’ Twirl ‘n’ Hurl and it'll be there decades after despite being essentially the same basic ride and having an IP connection.
Same with the Mad Tea Party cups vs. Storm Force Accelatron.
Why?
Which do you think is more timeless - Peter Pan's Flight or Cosmic Rewind?
Which is more likely to get a complete retheme in the next 20-30 years?
Why?
They're both IPs, right?
Haunted Mansion isn't based on a pre-existing IP though they've tried multiple times to launch movies from it without much critical or financial success. Do you think anything in Hollywood Studios is likely to outlive it?
My point about ET was that was literally the only thing to hang on. Murder She Wrote sure didn't. Fantasic World of Hanna Barbara didn't. Earthquake didn't. Ghost Busters didn't and neither did Twister which replaced it. Friggin' Back to the Future (which wasn't even an opening day attraction) didn't.
ET's frankly the fluke and there are strong rumors the reason it has lasted has more to do with Steven Speilburg's affinity for it and their working relationship with him than the 15-20% of Universal fans that would be ready to riot the way so many people are about a river and attractions on it that most of them don't even regularly do in Disney.
Disney cultivated the strong emotional attachments much of their audience has with them over generations. Current management seems happy to exploit that but apparently doesn't see near-term profit in working to maintain it.
