My impression is that the full loop of various Bill Nye lessons periodically delivered in the Great Hall was always much longer than the time the average guest spent in that part of the queue. This is true now more than ever because the FP merge point being in there means standby riders spend even less time in the room.
This is actually a good thing in a way- it means that guests who take repeat rides are less likely to hear all the same material every time.
In my opinion, every attraction that has audio or video components to the queue should make sure that those elements are long enough that guests at least won't hear the same thing twice, and if possible, much longer. Even when the audio/video is important to convey the story of the attraction or deliver safety information, the use of multiple variants in the delivery makes waiting for the attraction that much less monotonous.
