[T]he idea of a cast of regulars numbering in the dozens is also a consequence of 21st-century sensibilities, in that a plot line without a large (and of course diverse) variety of social entanglements seems too far outside the range of experience for the half-mythical millennial viewers who inhabit Hollywood’s stereotype factory. How can you relate to characters who aren’t constantly sidetracked from grubby issues like survival by trivial interpersonal drama? Who could live like that??? At my age, I’m more inclined to sympathize with the robot.
There is, perhaps unsurprisingly, a market for trivial interpersonal drama, albeit not a particularly discerning one.
