Same, if the Knightmare scenario is what they're looking to do for the Justice League film then that's ballsy as fuck and I'm hoping they stick with their current plans.
While 800 million isn't bad. The movie could and should have made more. That said they don't really need to change much in the short term. SS is coming out. It's done. I think that will play much better with critics and audiences imo. Most are excited for WW so a good trailer could really increase the hype. If those movies can do 700-800 million in their own right WB is on a good course imo.
They probably just need to have more control over JL. Making sure it stays the course. They really don't need to change anything. The tone is fine and JL is supposed to be more lighthearted although I'm sure still serious. But at the end of the day JL should be your typical superhero team up movie. I think there will be so many fantastical elements to it that you just gotta have fun with it.
