Batman is probably the most successful DC character when it comes to films and franchises
Wonder Woman did her thing and her sequel movie will probably be just as successful
Supes on the other hand has failed to really adapt to modern times.
Captain Marvel "Shazam" did really well and he's basically Supes but better. Better powers, less vulnerabilities, better costume, especially the Cape .
We don't need another Superman reboot. Just replace him with Captain Marvel
