Make this R - Rated.
It would be so weird if DC fumbled with the Justice League, but starts to find some success in horror. They're in an awkward point where a next character to bring out is Supergirl, but that would be after Captain Marvel comes out.
What if instead, they could look into a solo film for Lobo.
Could this also have Harley?
The dark knight concept looks like burn victim Val Kilmer.
