I think they’re in a tough position with dark rides. On the one hand dark rides are a defining feature of the Disney Parks, very much iconic. On the other (spicy take warning, lol) new dark rides often don’t really impress people in 2023. It seems that the dark rides with serious appeal all have a heavy dose of nostalgia attached (or, for those too young to be nostalgic, a sense of history, in the way that walking around a colonial era town like Williamsburg is charming.)
I know there are the usual complaints - too book report-y, too much unused space, not enough animatronics, crappy animatronics. But when push comes to shove, I think today’s generation, with so much technology at their fingertips, are just not wowed by traditional dark rides in quite the same way. This leaves Disney trying to find ways to “jazz them up”. I think there recent attempts with Rat and Runaway Railway are a step up from Little Mermaid and Frozen, but still not quite… there (wherever “there” ends up being) yet.
