I'd say you shouldn't discount the "showing your age" bit. For me lot of mature shows have kind of devolved into "look at all the adulting happening" themes which, at least to me, are kind of sad in how self-congratulatory and self-affirming they are.

It's like a window into a bunch of writers trying to make peace with getting old, while trying to "say something" about a middle class problems they've immersed themselves in.

Just my two cents.
