oh a show like that can be VERY entertaining if done right and realism seldom plays a role in that regard. One of my favourite DC comic series was a book called Gotham Central a police procedural comic-book series focused on the Gotham City Police Department and the difficulties of its officers living and working in Gotham City, home of Batman. While the cops did the hard work, ultimately it usual was a costumed super hero who solved the cases, but that doesn't mean it wasn't fun reading about the GCPD detectives.I honestly think there are fans who would eat it up. People seem more interested in Star Trek being "real" than it being "entertaining"
Likewise, the TV show Powerless, also set in the DC universe, followed the non-adventures of the R&D departement of Wayne Security, a subsidiary of Wayne Enterprises. The show was actually pretty fun but was sadly cancelled after 9 episodes.
