For example, Man of Steel showcased a Superman so conflicted he couldn't even remember what colors Superman wears.
Reboot Suggestion: Mighty Morphin Power Rangers
"I know one of them is red. The other one is ... grey?"
We're assuming the upcoming Power Rangers reboot has a new, gritty plot well in hand, and so all we're going to suggest is that they make the palette as bleak and hopeless as the new world the Rangers will face. If you're unfamiliar with the Power Rangers story, it involves 6 high-school-age teenagers who are called upon to fight evil as the Red, Blue, Pink, Yellow, Green, and Black Rangers (shown in order below):
The Black Ranger is black and the Yellow Ranger is Asian. I'm not making this part up.
Now that I'm looking at it, I can see how this might present a problem for keeping track of dialogue, but that just plays into the realism of the confused and conflicted world we live in. Who is wrong? Who is right? Which Ranger is talking right now? Didn't that guy get captured earlier? It's full of questions we can't answer, just like your NSAs and your Fergusons.
