We like to make fun of MCU, but WB and Sony stuff has shown how genuinely retarded a lot of these big company committees are, they are operating as if they had no data past 2007. They have literally no idea what people like, Feige with his faults generally does know. So like introducing Guardians as a flagship, or starting with Iron Man are lucrative risks, making a "universe of Spider-Man side characters" is corporate autism trying to grasp at a trend for appeal.
The smartest thing DC has done recently was try to get in on the zoomer filmbro action with Joker and The Batman. Dune was not perfect, but the mainstream discussion around it showed that the MCU pushback can be capitalized on. Just get an artsy director and make standalone stuff. They should get Eggers to do a Flash or something.
