Now what also stood out is just how dated the film had become. BTTF was opened in the early nineties... think about that.. almost 10 years after the original EPCOT and several years after the original MGM. The 'future' stuff like computer animation in the video was just awful by today's standards (rotating pixel mapped polygons).
Which made me think.. look at how fast BTTF dated itself.. why? The films themselves are still awesome! The attraction experience is basically the same as Startours, etc. Then it made me realize.. all those TVs Disney and Uni put in the queues in the 90s to keep you occupied while you waited... they were the albotrosse around the attraction's neck! They bring the whole attraction down. You can see that in T2:3D now too.. it's the film elements in the preshow that date the whole thing so badly. So here we have attractions roughly 20 years old that were basically as bad as 1950s scifi.. but yet we have attractions like IASW and POTC that have lasted twice that long and don't feel dated. The difference... no TVs in the preshows! And to think, they didn't have to waste time and resources producing that stuff either.
I rode BTTF once in California when I was maybe 8? I remembered it being pretty awesome. Watching the full experience remaster thing now I don't think the preshows dated the ride nearly as much as the main ridefilm did. Or if they did, the way they dated the ride wasn't detrimental to the quality of the experience...it was more of realistic immersion in the late 80s/early 90s which gets broken by the models and motion control effects of the ridefilm.
Not entirely sure the preshow is the problem...having a ride with a continuous narrative necessitates the exposition that usually only a preshow presentation (however it's integrated into the experience) can provide. With Pirates and Small World, you're given these loosely related vignettes that each last forever. There is really no concept of time in these attractions- no linear storytelling.
