As hard as they try, the DCEU films will always be limited by its shaky foundation. WB wanting to play catchup with Marvel is really coming back to haunt them. Instead of focusing on tighter stories, they have to throw multiple storylines and introduce new characters into single films. There was no need for them to rush and do a Justice League movie with so little groundwork. DC still has the two most popular superheroes ever with Batman and Superman. They would’ve made just as much money if not more than Marvel doing standalone, focused movies on one superhero that would’ve given their characters enough proper development for Justice League.
Imo, they should’ve done a proper Man of Steel sequel, then a standalone Batman flick establishing his DCEU persona, then a standalone Wonder Woman film. Then do either Aquaman or a Flash solo movie, THEN do Batman v. Superman, THEN do Justice League. Just would’ve made their storylines a lot more focused and less convoluted and it would’ve given the filmmakers more freedom to focus on a tight story rather than having to throw in plot elements that should’ve been handled in their own standalone films. Ya’ll can throw in feminism all ya’ll want but the real reason why Wonder Woman is the most successful DCEU film up to date is because it has the tightest, most focused storyline and is committed to one character, not forcing a rushed, shared universe.
