Honestly there’s only two versions of Batman you can watch to get Batman at his best
(Specifically on the human side of Batman that Hollywood overlooks)
-DCAU Batman: Particularly in episodes like Heart of Ice, Baby Doll and It’s Never Too Late, as well as the Mask of the Phantasm
-Brave and the Bold Batman: Mainly the episode where he re-encounters Joe Chill, the guy that shot his parents
Other than those two, you’re free to skip all live action and animated versions of Batman to understand him
