From FandomWire: "EXCLUSIVE: WB Developing ‘Superman’ TV Series"
Supposedly, Warner Bros. is working up a Superman TV show because Justice League was a disappointment, and Tyler Hoechlin's guest appearances on Supergirl were well-received. He will appear as Superman in this year's Arrowverse crossover, and that will serve as a back-door pilot.
I have mixed feelings about that. I've really liked Hoechlin in his appearances on Supergirl. But I don't know how much I want or need yet another show about Superman, and I wonder how much such a show would drain or dilute Supergirl (which is a story I haven't already seen before).
Yeah, the only Superman series I'd want to see is the one that takes him off Earth to explain why he never shows up in Supergirl when the whole Earth is in peril. That could be a miniseries!
