okay but also like. within the batfam i would argue that the good ol' days continuity problem mostly exists because of zero year
like within the version of batfam continuity that existed 1986-2011 (which is to say mostly post-crisis but also extends backwards to some pre-crisis/bronze age stuff that remained the same) there was a type of darkness that began to make itself known only after dick left robin, which can be summarized as "crossover events" -- no no wait i'm serious come back
like. dick leaves robin. spends the 80s going through a bunch of truly harrowing shit in new teen titans. crisis on infinite earth happens -- mostly important in a comic-publication sense, because after coie dc starts having yearly company-wide crossover events where the world is placed in existential danger!! in fact, in the very first post-coie crossover event, legends, jason is very badly injured. then we have jason's new, darker backstory, and the storylines leading up to his death. we have batman: the cult, which i mention because it's one of the very last jason robin stories and also the precursor to what i'll call the Gotham Is In Disarray Event.
the Gotham Is In Disarray Event can be summarized as: some malevolent force has taken over gotham, on a city-wide scale. the bats, police, and civilian government are fundamentally not in control of what is happening, and you (an ordinary civilian) could die at any time!!! spooky!! the ur-Gotham Is In Disarray Event is, of course, no man's land, and since no man's land Gotham Is In Disarray Events have happened regularly since -- in recent years, at a near continuous rate (city of bane, joker war, fear state, failsafe, gotham war --)
so dick left robin, and then Gotham Is In Disarray Events started happening, and escalating. this makes sense! robin dick faced problems, but they were "nearly dying at the hands of two-face" problems, rather than "everyone in america's third-largest city is being joker gassed at once" problems.
except. of course. except for zero year.
zero year is a classic Gotham Is In Disarray Event. of course it is! i'm sure snyder took inspiration from nml and other post-crisis Gotham Is In DIsarray Events. and it is, obviously, one of the very first things that happens to bruce as batman. and it's still canon (see: new history of the dc universe), because it's the only batman origin story we have that's not 40 years old and written by frank miller (although. b:yo is also still canon. do NOT think about that one too hard.)
what are we to make of this??? have Gotham Is In Disarray Events been happening the whole time????? THROWS UP HANDS.
