Sorry, but if they intend to not make any of the superheroes as live action, why keep holding on the rights? To prevent anyone from making the films, or what? So that we NEVER will see them on the big screen?
Warner Bros are not worthy of the rights, just as Thor was banned to earth and not longer worthy of Mjölnir. (I just had to make that superhero comparison)
We deserve to be treated better. And it's not just comic book fans that like sci fi, fantasy and adventure very much. Others do that too.
DC have heroes with different themes. It can be about space, mythology, ancient times, other dimensions etc. Everyone of them has a sense of wonder and escapism: Wonder Woman, Aquaman, Hawkman and so on.
Why should we be denied this?
