Is there any proof that he did these things in reaction to the announcements of those films, or is it just speculation?
Because WW and BvS (at least before it came out and people witnessed it lol) would be believable things he'd want to compete with, especially at the time, but by the time New Gods was announced I can't imagine DC/WB was establishing any trends he'd want to rush to compete with anymore. Even their successes are too sporadic.
