The DC Universe felt a bit one-note in its most recent on-screen incarnation. The franchise tried to copy the success of the Marvel Cinematic Universe without the level of restraint it employed on its way to the top. With the DCEU over and done with, the new DCU needs to take a lot of new directions. One way to mix things up would be to dispense with superheroes entirely and try out a few new genres. They may have that idea in mind if they are truly planning on making the rumored Sgt. Rock movie.
