I'm going to avoid my own biased history here and look at this through the eyes of my daughters who at the time of this story (August 2017) were 12, 10, and 7.
We started our trip with 2 nights at Universal Orlando. 2 Nights, 3 days with Universal Express thanks to staying at the Portofino. They all loved Wizarding World. We then knocked out the rest of the parks and by the end of day two all three commented "The other rides all feel the same, can we go to WDW now?" The third morning they simply requested to do Forbidden Journey again but then all three voted to leave early to go to WDW. Side note, my 7 year old DID love RipRideRocket but I'm thinking in retrospect this more due to the fact that it was her first "big" coaster.
I bring this up because after multiple days at WDW, the unanimous "favorite ride" for these girls was Flight of Passage. So while I think of it as follows:
- Is it screens? Not entirely. Yes, they got bored of Universal's repetitive screen based rides but loved Flight of Passage...a screen based ride.
- Is it IP? At first I was thinking that the IPs of King Kong, Transformers, Simpsons, MiB, etc didn't apply much to them (they haven't seen any of those movies) and while I think that's an issue, none of them have seen Avatar either. Yet minutes after riding my youngest was walking around with a Banshee on her shoulder.
So for me it comes back to a hybrid answer of...it's all about what you do with the IP and technology. For my girls Universal (outside of HP) felt like a constant barrage of let's throw 3D things in your face rides that they quickly tired of. We visited again this month and not one of them asked to go back to UO despite a deep love for HP.
Just sharing a perspective...
