WB: "What? Wonder Woman can't fight and behead Steppenwolf, that's too scary! Kids won't like it. Let Superman save the day even though Wonder Woman's fought beings from other worlds and/or gods before. And Barry being a forensic scientist? Not relatable, let's have him be quirky and talk about not liking brunch. Make Steppenwolf more expressive and design him like Darkseid's distressed grandpa in a Skyrim cosplay, it makes sense for the movie, trust us."
Also WB: "Let's disrespect Wonder Woman's body by having the Flash nerdily fall on her boobs in a cheap callback to Banner/Widow in Age of Ultron, and then disrespect her integrity in WW84 where she violates some dude just because Steve is hijacking that man's body! Kids today love Revenge of the Nerds-type 80s tropes and writing, yeah? Uhhhhhh Steppenwolf who? Oh yeah the guy that got punched a bunch by Superman and is offscreen eviscerated by his own minions. Kids won't notice how horrendous a death that is, we're sure!"
