Eh, sounds like squandered potential. Like almost everyone else in here has said, if this was a Gotham Central-like series, I'd be ecstatic. But a pre-Batman Gotham is simply a massive loss in potential. Dent, Sionis, Maroni, Falcone, Thorne, plus countless villains we know they will try to shoe-horn in like Scarecrow, Riddler, and Mad Hatter will be much better emphasized in a post-Batman world.
Of course, this is nothing short of a response to
Agents of S.H.I.E.L.D. The cat is out of the bag. DC Comics, try to at least be grandiose competition, not straggling behind.
