Honestly asking: If guests don't care for high-tech rides, screens/projections, and in-depth backstories, why does Disney keep moving in that direction?
A few things to consider here:
1) It's easy to confuse the average everyday "guest" with us on the forums who tend to "complain" about the direction Disney is going. For a lot of us here, it boils down to a perceived lack of originality/quality or even just a baseline of imbalance with what is coming out of the Glendale offices with regards to IP infusion. The Joe Everyman guest who brings his family once or maybe twice a year, largely just gobbles up whatever Disney churns out without batting an eye.
THIS is the type of people Disney builds for.
2) Why are they doing this?? Simply put, their competitors are doing it. New technology in the themed attraction medium is still largely growing and in some ways, catching up with the growing technology in the real world. But, as we've seen with certain things like
Mario Kart, it just feels like it's lacking and those of us who cherish Disney for the way they've largely done things, don't want to see things ruined by whatever the new techno trend is. There was a time when Disney used to be the leaders in their field, but now it seems that they've become the followers.
3) Money. Screens and projectors are much easier to implement and swap out/upgrade as opposed to ripping out entire sets, AA's, etc. every time you want to make a change. It was easier for Disney to throw in some projectors on
Maelstrom vs. building a new
Frozen attraction from scratch.
4) The backstory "issue" is a complex thing. Over the weekend I was listening to the
RetroWDW podcast episode on
Pleasure Island and it included a lot of relevant anecdotes about things relating to backstories. When it was first unveiled in 1989,
Pleasure Island (what is now
Disney Springs) contained a very elaborate "backstory" for almost every building complete with a hung plaque to let visitors know the story. The hosts commented that this was largely Eisner's doing and it also happened to coincide with the rise of things like themed restaurants (Rainforest Cafe, etc). All of a sudden, stores and restaurants weren't satisfactory enough on their own anymore... everything needed a
reason for being there. But, like the hosts said...
no one cared! Pleasure Island wasn't a huge success out the gate and received a major overhaul less than 2 years after it opened.
4.5) Now, I'm not suggesting backstories came into being during Eisner's time (as I've stated elsewhere, virtually
everything done at Disney has contained a backstory of some sort) but really for the first time, these extra ancillary bits of trivia were shoved out into the open with the expectation that guests would stop and read a plaque (or in modern cases, be forced to watch a queue video) in order to fully understand what it is they're about to experience. Classic attractions such as
HM,
POTC,
JC were designed in such a way that they didn't
need these added elements to bring the guests into their world.
