Shame about Stargirl. Hadn't actually watched it yet, but look forward to soon.
Its interesting how the JSA has popped up quiet a bit in adaptations over the last 10-15 years, albeit as supporting/guest characters. They've been in Smallville, in DC's Legends of Tomorrow, in Stargirl and now in the Black Adam film.
Way past time they get to headline a TV show or movie. Hopefully the DCEU has solo plans for them!
