That's one great thing about the Stargirl show.
It got my daughter interested in the comics. She's tearing through that JSA run now and loving it.
Since that run followed up Kingdom Come, after years of me telling her she'd like it, its in her "pile" to read.
I agree having Captain Marvel as a regular is preferable...but doing the cross over story and bringin in Routh for that is something I'd be on board with.
Don't know if warners would allow for Cap to show up, as he is in movies, might be hands off like Bats, but do not want to see Brandon as Supes go to waste, as would rather have had him in a series then new Lois and Clark one!
