A bit of both. Now to be fair, it’s not like they’ve lived through the shrinking of show time to the extent many of us have, so the pacing is understandably a bit foreign.

But there is also the different energy level. The overall look matches an overall higher energy level, and the pacing seems to likewise reflect that. Could they maintain the energy level with a few more minutes? I think so, but it’s purely hypothetical.
Bob, even in what could by consensus be called his prime, just leaves them “blah.” It’s just one of those fairly common generational things. Of course there are exceptions, but in many pop culture areas, golden years tend to align with youth.
