I always thought it was very cool that if you watch the DCAU shows and movies chronologically, you can piece together pretty much the entirety of Bruce Wayne’s life. Really speaks to the cohesiveness of the universe Timm and Dini established.
I like this too. Except the “40s” one he is actually still in his 70s or whatever lol. He was temporarily rejuvenated using a Lazarus Pit. But yeah, I still think it’s cool.
