So on a slight tangent... since we're talking about SSE, dated pavilions etc
On the bluray for the Back To the Future trilogy - they have ALL the videos, and a simulation, of the BTTF ride from universal.
What stands out when you watch something like that out of the original context... is you notice JUST HOW MUCH WORK there really was in those things. The amount of video shot and produced for just the preshow of the attraction is quite mindboggling. For those that don't remember, they had fake news reels, a whole setup of Biff in the facility, etc. The amount of film just dwarves the actually attraction duration.
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.
So that's my tangent on preshows... the reliance on video in them will probably shorten the life of your attraction! So don't do it! Use real people instead
