More Gotham!!!
I think this episode especially does a good job of demonstrating the shows goal.
As in, 'now THIS is the type of place that will need Batman.' Like, in this one we get a crazy balloon vigilante - years before Batman is even a thought. I like that because I personally think it's better when we get people like this and his rogues gallery before he becomes Batman. As opposed to like, a switch flipping and just everyone deciding 'hey let's go nuts now that there's a hero running around.'
It's showing that the city is already a crazy place that will keep building and building to when Batman arrives in another dozen or so years.
