I would say that you're comparing Apples and Oranges, but to give my opinion on your questions:Oh that actually sounds amazing?
Not to be like “this generation...” or whatever but why on earth did Universal give up on actor and/or practical effect-led attractions that felt Hollywood? Beetlejuice, Twister, Earthquake, and I guess now also Terminator, I’ll miss you...
To keep this on the HHN theme with the thread, it almost feels like that’s the only thing still keeping the park feel production-based. During the regular year, Fallon is maybe the closest thing to “look how entertainment is made!” but you also go into space, so, yknow...
But HHN employs the use of so many neat practical effects, and when it does use screens, it tends to use them very, very effectively, and I miss that about older attractions. Yes, the image quality of Fast and Furious is notable, but I’m living for that actual spectacle and awe that comes with last year’s flying witch and this year’s bungee Wolfman, yknow? That’s probably why I’m so into the event, beyond the general artistry.
Behind the scenes/Ride the movies aesthetic - This changed based on the pallet of guests that wanted more immersive environments and worlds, Harry Potter really ushered in this era as the new template to base theme park attractions around. I suppose they felt that changing from 'look how your favorite media is made' to 'step inside a fully realized world of your favorite media' is much more exciting to the average person and much more lucritive to the resort as a whole. This honestly makes a ton of sense, and I personally don't think that Universal has lost any edge in this regard. When you think about it, HHN has adopted this model just as much as the parks.
Screens vs practical - I think here is where the parks have lost a bit of magic but seem to be steering back. To be honest though, screens are reliable, predictable, and provide a consistent ride for a much lower price tag. I get it. I think Universal saw this opportunity and ran with it for a while, now I think they are understanding their model and what people want no longer support rides like this. In other words, the immersion must be seamless and screens in their current iteration just can't deliver on that.
Set driven/practical elements of HHN - To be honest, it's not like HHN has a choice of whether or not to be a practical/set driven event. At the end of the day an event like HHN will always be theater. Where I see them losing a bit of edge in the coming years is with their creative scare tactics. The obsession with creating a 'scene' rather than a 'scare' may start to bite them in the butt a little, but we shall see. Overall, HHN is pretty locked in with what they can/can't do. I have seen more projection used at HHN, but I don't think it is in any danger of remaining practical...It has to be that way.
Side note: do we think Braillard is the next Aiello?
