People were complaining about Burton's Batman killing back in 1989 for goodness sake. And some view Nolan's Batman as being "hypocritical" to an extent for preaching the no-killing role, yet people die because of his actions in all three films (albeit not intentionally on his part).
It's been a thing for a long time. Also I have to LOL at anyone who claims that WWE and Aquaman were "failures" because that's nonsense. And Shazam looks like it's going to do very well as well.
