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.
