That's an odd choice for the first three rides...
The "something goes wrong thing" is a result of a change in the philosophy behind theme park rides that has been underway for decades now. As "immersion" and, particularly, "immersion within a copyright-able fictional universe" becomes the goal of theme parks, the guests role in the story must be explained. You are doing something relatively normal and "Something goes wrong" is an easy explanation for why passengers are part of a thrill ride narrative. Disney does it with most of their modern rides and virtually all of their IP rides, including Star Tours (both versions), Mystic Manor, E:E, Dinosaur, Stitch, the original Kilimanjaro Safari, Kali River Rapids, Indiana Jones, ToT, the Hong Kong Iron Man attraction, HIStA, Philharmagic, etc.
There are variations within the roles assigned within these Disney attractions, of course, just as their are at Uni - in Transformers you're a NEST Agent, in Spidey a reporter at the Bugle, at Despicable Me a new minion - which get set up in the pre-show. If you look only at the ride plot in the broadest terms, however, they tend to be identical.
"You are doing a thing and everything goes exactly as expected" doesn't really work for attractions that are meant to offer any sort of thrill - it's one of the big problems with M:S.
The old model, of course, was simply not to offer a narrative for guest involvement. Why are you on board a runaway mine train? Because you are, Why are you in a cart moving past scenes from old animated movies? No particular reason. When Disney tries this model today, they tend to get criticized for book report rides - witness Little Mermaid (even Mermaid attempts to situate the rider within the narrative via Scuttle "telling" us the story).
