I finished the first adaptation of Batman (1943) -- pretty goofy but it grows on you. The 1960s TV series is a parody of the 1940s versions.
It's not for binge watching because it's so damn formulaic.
Batman initiates about two fistfights every day, usually outnumbered 2:1. He could just call the cops but what fun is that? So he gets a sound thrashing and narrowly escapes death, until next time.
There's no gadgets or Batmobile, none of the well-known villains. But it's still kinda fun.
Includes some WWII anti-Japanese sentiment, the most outrageous example being >>5552
