The real problem of WB is exactly that: they allow directors to dictate what the movie should look like and what rhe story of the movie should be. They have no vision of how these things all fit together, so they throw that shit at hollywood directors who themselves dont know how this shit fits together because they couldn't give a fuck about any of this and are hoping their movie gives them a bigger career. See Ayer. Dude clearly doesnt give a shit about or understand the DC verse. He watched one SS movie, then decided to file a complete script with WB within a few weeks.
All of these dumbass directors thinking they are the next Nolan. Honestly, Nolan didnt give a shit either, but at least he had the talent to make movies that were all at least 50% good.
If WB wants Marvel money they need to do it like Marvel.
Have their own vision and work themselves up to it. Release 2 DC movies per year. Start with a real Superman movie, then follow up with a real Batman movie. Then the next year have a JL movie. Then have a Flash movie in the same year. But in all of these make sure there is a plan to connect these characters with us and the DC verse. Stay on schedule. Hire directors who are nerds and familiar with the material but have no big budget experience. Dont hire them just because they have oscar buzz, if anything avoid in these cases. Also, get rid of this shitty Unreal Engine design, that shit doesnt sell.
Release CG animated 3 DC movies to expand the universe every single year.
