I have mixed feelings on this. On the one hand, yeah, they could use a fresh start. But at the same time, I really like the casting of The Big 3 (Superman, Batman, and Wonderwoman). Everyone else ranges from “eh” to “nope”, but I wouldn’t want to lose the 3 for a reboot. That said, if it means a really good Justice League movie down the line, by all means. My opinion of Justice League has become a bit more realistic since I saw it. I still like it to a degree, but Infinity War didnt do it any favors.
