Basically, if the character is meant to be dark and gritty or the reverse, embrace it.
If you're trying to make them something they're not because another superhero style was successful, don't be surprised when it blows up in your face.
I suppose that in all the years that Warner Bros. has owned DC Comics, they've never been able to market them effectively, except for Batman and Superman. Meanwhile, look at what Disney has done with Marvel Comics; they're doing better than ever under Disney's ownership.
And I would like it if DC changed styles to be more of Marvel's fun, action-adventure style, instead of the grim and gritty style they've been doing lately. I hope Warner Bros. can get it right, so that they can make DC bright and colorful again, like they were in the 1980s and 1990s.
Is that your final answer?
