I love this, always up for a new Superman or Superman related series, especially with Krypton sadly cancelled. (Season 2 was so good, such a shame).
My only concern is the idea of Superman and Lois having a kid being the focus. Brandon Routh will attest Superman having a kid didn’t work so well the last time they put that on a screen. I know that Superman and Lois have a kid in the comic books, but the non comic book readers don’t.
But even so given it is a spin-off of the Arrowverse, which seems to be unable to make a failure (some whining the shows are “too political” insist they are failing… but the newest CW superhero show is Black Lightning with seasn 3, and all the Arrowverse shows are on at least season 5… yeah most shows wish they could fail that badly). And it’s Superman. Krypton sadly broke the 100% success record that Superman and Superman related shows have had up to this point. But a spin-off of Supergirl about Superman… sounds like a can’t miss formula.
Won’t lie… not sure I love the Lois Lane casting, but she will grow on me if the show is picked up I’m sure.
