^ The Incredibles and X-Men both worked well as ensemble superhero movies without giving either team origin stories.
didn't quite pull it off, because it mainly introduced the team by having Charles give Logan a really long, stilted expository speech. I'd rather see something that's truer to the "show, don't tell" rule.
Though I'm still not convinced that it's a good idea for DC/WB to put all of their tentpole superheroes in one movie without some groundwork being laid down, the way Marvel did with their solo outings.
I'm not entirely convinced
it would work myself, but I certainly think it would be interesting to try.
