Until the fifth episode of its second season, “Grown-ish” didn’t seem to understand its target audience. A cursory glance at the show could suggest otherwise. After all, it seems to have all the fixings of a show that would appeal to a Gen Z audience. The cast is hot and diverse. The show’s Twitter savvily abstains from starting its tweets in upper case. Its Instagram features clips of its characters clapping back in a way that is just almost funny. And the premise of the show does seem like it could yield some relatable situations: it follows Zoey Johnson (Yara Shahidi) and her group of friends at the fictional university Cal-U. Each of the friends has one or two identities—Republican, Jewish, drug dealer, stoner—in which the writers have rooted their personalities, which are drawn just distinctly enough that they could be real people.
