Absolutely. Sensible companies will look back at the DCEU as an example of what not to do. They literally butchered the biggest names in the superhero business while Marvel used characters like Iron Man and Thor whom the general public didn't even know much about and made a fortune out of them. DC literally had the rights to all of their heavy hitters, a ton of money and a great reputation coming off of Nolan's triology. Instead of playing their cards right for long-term success which would've been guaranteed, they chose the quickest and most half hearted route they could.
