Hoping to see a better version of the Justice League in the CW DC Universe? Well, it looks like (outside of Superman showing up on Supergirl) that won’t be happening, and the producer of the “Arrowverse” (the Green Arrow series Arrow having been the start of the CW DCU) has shut down anything more than Easter Eggs for the future. Too bad, but since Supergirl exists in an alternate universe and Superman has shown up before maybe he’ll pop up again. I liked him on the show. I also want to see Black Lightning take place in Supergirl’s universe because last I heard she didn’t have enough superhero friends at home.
