The Muppet Show was VERY good -- totally on brand. It was a faithful recreation of the old show, with only hints of modernization here and there. It's like they picked up right where they left off in 1981. Sabrina Carpenter was a great choice to usher this in, because she's young but her style blends in with the show's tone. The humor was just as good, decent jokes, and no culture shock -- nobody's texting each other, etc.
They used technological innovation very thoughtfully, so that you'd barely notice it unless you were a true geek. The fact that they could cut to the audience more times per show, AND it's a combination of muppets and people, which gave them a way to bring in more celeb cameos like Maya Rudolph.
I hope they get to do whole seasons again -- if they're as good as this special, it'll be worth it.
