I think Mr. Weisman probably approaches any show he's working on with writing that is appropriate for the audience it's intended for, and in the case of Young Justice I think it was always more geared toward older audiences then just being strictly a "kids show."It's kind of interesting (or maybe ironic, I'm not sure) to see Greg Weisman coming back and making the show darker given how (except Star Wars Rebels), the shows he worked between 2013-2016 are Transformers Rescue Bots and Shimmer And Shine, which are lighter and softer than what he usually does .
On a related note, I remembered in the summer of 2016, where Genndy Tartakovsky mentioned about Samurai Jack season 5 how he would take advantage of the looser standards of Adult Swim while still not going that far, though the finalized season fell into that. Greg Weisman outright confirming the rating will definitely mean that this is a wild ride .
I'm still not expecting that marked a difference between Outsiders and past seasons, but I guess one could say the show has continued to "grow up" with each subsequent season in a way.
Even if this show dives into some heavy topics, I don't expect it's going to be anything like the DC animated movies, aside from having Phil Bourassa as a shared designer.The trailer and sneak peak didn't seem so wild to me.
What I liked about Young Justice was how serious it could be without getting too dark and depressing like DC's animated movies...
