I was there a couple of days and went on a few times, it was 10minutes maximum. I was there towards the end of the September, early October rather than end of October...perhaps a quieter time? I remember it clear as day, Jaws had a 45minute queue, it was stacked on that day.
Simpsons still gets good wait times, but keep in mind it has a higher capacity load then Jaws did. But yes, Sept/Oct are slower times (save for HHN).
The detailing in the videos and the props was absolutely amazing. The ride was well ahead of its time when it came out. The reason a lot of people bang on about the fact that it 'hurt' when riding it, or 'rose tinted glasses' is because a) they were old and past going on rides (it's a flying delorean ffs, do you want it to be like soarin..?!?!) and/or b) they were never huge fans of the trilogy to begin with.
Clearly, there are a few exceptions who were just not big fans, and they are of course entitled to their own opinion....perhaps from within their mental institute ;-)
BttF got extremely jerky towards the end of it's life. Nothing to do with being old or "rose tint glasses".
and ahead of it's time? It was preceeded 4 years earlier by Star Tours.
