Shit is epic. Well written. Spooky themed. Very film noir. written and produced by the same people that made the monumental best American anime of all time, Warner Bros Batman the Animated Series. In fact, Kevin Conroy who was Batman is the voice of old Bruce Wayne in Batman Beyond.
Of course nothing can beat Batman The Animated Series. That shit was superb, deeply thought-provoking as a morality play, with substantive character development and progression of cohesive narrative. Really, that show was like a novel.
Only that series and Tim Burton's original Batman movie I feel properly portrayed the perfect Batman.
