** The declaration of 2001 [[UsefulNotes/TheWarOnTerror being a bad year]]. That's all.
* ShockingSwerve: The reveal of Monarch's identity didn't make sense, as Hawk was of only average intelligence, had no tech savvy, and was dedicated to chaos over order, all in violation of Monarch's personality. This is because it was changed at the eleventh hour after the story's ending was leaked. Even worse, ever since then DC has tried to do damage control by ''also'' cramming the original plan in, until no one cares anymore who Monarch actually is.

* TechnologyMarchesOn: Accounted for — Matthew Ryder, before becoming Waverider, deliberately uses obsolete technology from the late 20th century incompatible with that of 2001, to prevent Monarch's minions from finding his plans if discovered. TruthInTelevision, since by 2001, computers and peripherals that could read 3.5" diskettes were already rare.
