As an aside, it was hitting some similar story beats that Black Lightning (another show by same production team ) did.... the father who is trying to be a good father and his kids didn’t know his dual identity and the kids start developing powers.
Though I’m finding this writing a bit more grounded ( not intended as a ‘lightning’ not being ‘grounded’ joke but I’ll take it
Though ( to me at least) one of the sons and off as excessively whiny beyond just angst at some points, so I hope that tones down a little but otherwise characters seemed written well for the show
