First Dwayne Johnson and the other cast members did excellent work with what little they were given as far as plot development. With that said, DCU needs to do a better job of not bringing in supporting heroes without providing an origin story. Take a page from the movie that started the current Super Hero wave Iron Man and don't bring in 4 heroes with no back story. Maybe I missed the movie that explained how the hawk dude, the wizard dude, the Ant Man wannabe and tornado girl were the core of the justice league??
