For old time's sake, my brother and I watched a couple of episodes of The Muppet Show on Disney +. Two things:
1- While the humor is not outright adult-oriented, there are jokes that are certainly bawdy enough that I imagine I had no idea what the hell they meant when I was watching as a little kid. Pretty impressive how the show has that Pixar-esque multi-generational appeal. It was family friendly but not the type of thing where an adult would just want to zone out while watching with his or her kids.
2- The production values and the overall execution were very impressive. When you think what these puppeteers had to do to pull that type of thing off effectively, it's really amazing that the show comes off as seamless as it does. Not that they were performing "live" of course, but even still it must have been tremendously difficult to put that all together.
Henson really was a genius.
