that's exactly how i feel. Gotham is the "Smallville" of Batman. Smallville had a bunch of Superman villains before Superman existed, and they completely changed the Superman mythology. I expect Batman to make changes to the mythology just like Smallville did.
If it's hard to swallow, people should try to accept that it's basically an Elseworlds take on Batman.
It's awesome to see modern takes on Nygma and Penguin, it's been so long since we've seen them in live action. Even though this isn't meant to be a definitive take on either of them, I'm interested in seeing both character's origins develop. IMO Batman's world is so interesting that it totally can stand on its own without Batman.
Bring on Tommy Elliot, Ethan Bennet, Roman Sionis and Harvey Dent as Bruce's schoolmates.
