I grew up with the Animated Series - which aged quite well - and Batman took mad Ls back then, was a much more ‘realistic’, deep layered and well written character. I dunno what happened but 10 years or so ago the internet n pop culture made him unbeatable - a parody like the Lego Batman lol - and I can understand why folks hate him nowadays ...
from a philosophical point of view I like to believe that the writers (and us) give him all these for a human unrealistic abilities and overcomes everything thrown at him because we want to believe that we as humans can indeed overcome anything if we are in peak physical condition with all money and resources at our disposal.
