At the risk of pointing fingers, the Muppets and their apparent unwillingness to branch out beyond pockets of Manhattan means they’ll never be able to lay claim to being genuine New Yorkers.
I understand this is satire, but the reviewer has missed the entire point of the movie. The Muppets weren't intending to take in Manhattan and become New Yorkers. The movie is called the Muppets Take Manhattan, as in they bring Muppet mania, their zany brand of madcap melodies, to Broadway to the benefit of New York. Of course they didn't see it all, you could live in New York for years and not see it all. The point was for New York to experience the majesty of the Muppets, not the other way around.
Also, to lean into it: they only took Manhattan because they didn't dare step foot in the other boroughs. Except for a bar in Williamsburg (I'd say one with skeeball but that doesn't narrow it down), they were super popular there.
A reminder that they accidentally made it canon that whether or not Kermit exists is along the chain of causation that determines if 9/11 happens in the Muppet universe.
