Mmmmm considering it's been almost 20 years just since the first book came out and a new generation is now reading, I'm thinking the park part will be around a LOT longer...
You are missing my point... Not saying Harry Potter IP isn't long term.
I'm saying when you mix IP and e-ticket (read popular, flagship ride) you have an issue. You have to manage two things (the staleness/age of the IP) and the ride itself.
When it comes time to redo HP because we've moved on to UHD 4K 3D is the norm, or laser hologram, or whatever... or the ride system is broke, or the format of the video is unsupportable, or any number of updates are required you have two problems:
- Fix the ride
- Update the IP without upsetting the world
How do you redo the film without the actors? And what happens when you revoice it without the originals? Or you need to freshen up the story? Or redo the special effects? Touch the "original" movie with the original actors and you've upset the IP fans. Leave the original and keep the older format/aged look and you've upset the e-ticket fans.
Space Mountain, Thunder Mountain, Matterhorn, Expedition Everest, Test Track don't have those problems. You can do whatever you want... without worrying about keeping true to the IP.
Cars Land, Harry Potter, Star Wars Land, etc all have that risk. They risk being overly expensive and overly complicated to update... Not a fact, this is an opinion. There is not enough history... but based on the flack Disney gets for updating IP Dark Rides... I can only imagine what happens when someone touches an IP E-Ticket. It's gonna be pandemonium.
I will say the HP universe is very interesting... they are now starting to do the challenging part. How do you expand past Harry and team to new characters, OR how do you replace the original faces. Interestingly they are trying both simultaneously.
Star Wars was interesting because they only tried re-casting a couple of bit players and a much younger Obi-Wan... everyone else essentially was in a costume or unique to their era of films, or the original actor. Once they start messing with younger Solo that might get bad (or good) though.
Point being (on topic)... RnRC would be much better with a generic theme. Attaching it to an IP comes with all the baggage and headaches an IP brings. Just look at Avatar. If Disney had said - here's this really cool E-ticket ride where you are on a flying dragon and another where you are on a Pirates type boat ride through an alien land of unique creatures and glowing plants - everyone would say "OOOOOHHHHHH I like!!!"... but once they said ... "Avatar..." you got a boatload of "I hate that movie therefore I hate those rides before I ever see them"... IP baggage.
