s1e3 "The Balloon Man"
was one of several season 1 episodes that focused on how pre-Batman vigilantes, bizarre villains, organized crime, and a corrupt city government defined life in Gotham.
Both are must-see shows! Fun fact: Smallville exists due to a Batman prequel, "Bruce Wayne", that got axed because of the TV Bat-Embargo. The idea got re-worked into a Superman prequel. #Gotham might never have been green-lit if not for Smallville's success.
