Stargirl” (Mondays on DC Universe; Tuesdays on CW) – one of 14 current TV series executive-produced by Greg Berlanti – falls into the category of what my buddy Michael calls “product”: something that exists for commercial rather than artistic reasons. That doesn’t mean it can’t be good, but this latest addition to the DC TV universe is as stiff as the Cosmic Staff wielded by its title character, teen Courtney Whitmore (Brec Bassinger, “47 Meters Down: Uncaged”).
“Supergirl” (8 p.m. Eastern Mondays on CBS) is a slickly produced and nicely acted but utterly unnecessary and unimaginative addition to TV’s comic-book superhero boom. Because it’s in the same timeslot as another DC adaptation, “Gotham,” and the year’s best new show, “Crazy Ex-Girlfriend,” my DVR wouldn’t record it and I watched it on the Internet. It was hardly worth the extra effort.
