The classic live-action 1960s Batman TV series starring Adam West and Burt Ward
A show that, while usually described as 'campy humor', was a success due to how all the actors were phenomenally awesome and because they played their roles very seriously. This show was also responsible for the Riddler becoming popular enough to move to A-list Bat villains and for setting the foundation for Mr. Freeze's origin that would later be refined and made canon in Batman: The Animated Series.
It ran for three seasons and one movie set between seasons 1 and 2
