If nothing else, this series deserves one for its use of the Calendar Man. Lame, forgettable villain with a dumb gimmick? In this comic he's a Hannibal Lecter-style genius, who clearly knows the truth behind the Holiday case, and enjoys rubbing it in Batman's face. Not just his personality is improved on, his appearance is also greatly redesigned, giving him an almost albino skin and an always-calm demeanor.
Batman's fight in the climax, where he takes on Mad Hatter, Scarecrow, the Penguin, Solomon Grundy, Joker, helped somewhat by Catwoman.
Batman stopping Joker from spraying a square with poison gas on New Year's Eve, fighting him aboard the crop-duster.
