Which would be a better choice to read for a person how hasn't read a batman comic before.( Batiman: Knightfall or Batman new 52. ) Help would be appreciated.
Uh, neither, if you're just starting off. If you want to get some real perspective on Batman & The Joker's relationship, start with Batman: The Killing Joke. Or, hell, read Batman - Arkham Asylum: A Serious House on Serious Earth, the original inspiration for the Arkham Asylum game. It's not note-for-note, so don't worry about spoilers!
