What stands out about “Black Lightning” are not the scenes in which the title hero zaps a gajillion volts of justice through a crew of murder-minded gang members. You can already see that sort of thing on CW — home to “The Flash,” “Supergirl,” “DC’s Legends of Tomorrow” and “Arrow” — and the rest of superhero-supersaturated TV.

What you don’t see so often on this youth-oriented network is what happens after. Jefferson Pierce (Cress Williams), the hero’s middle-aged alter ego, lies in bed, sore and moaning from the exertion. “Black Lightning is getting too old for these streets,” he says.

The other distinctive part of the show is, of course, the “Black” in the title. “Black Lightning” is immersively, not incidentally, black: The good guys and bad guys, teachers and students, victims and criminals and reporters are mainly African-American.
