Except the effect with the xenomorphs which at one time would elicit an audible response from people with the one in the ceiling often getting guests in the car under it to kind of duck, in later years, were creating barely curious glances in all the ride-throughs I'd been on.
The movie might be a scifi-horror classic but it's representation with the Ripy animatronic
(can a rotating head on a manquin be called an animatronic?) and the anything-but-scary xenomorph interactions were not.
It went in there representing something intended to be current and if all that ride was going to end up being was a tribute to classic movie scenes with all the "current" stuff lumped into the reel at the end, of course it was going to lose the interest of an audience that over time would become more and more disconnected from the main draws of the attraction.
I mean even some of the classics like Casablanca - sure, most people have heard of it but how many people under 40 have ever seen it or really have any clue what it was even about?
If it's a classic and needs to stay, what other things could be replaced, then?
With something like this, you can't keep it
all and expect it to work for 50 years. You gotta pick and choose what you keep and what you update so that newer generations will continue to find it relevant or you end up with... MMRR... which... is the direction they went.
