Grant Morrison's Arkham Asylum: A Serious House on Serious Earth is the best Batman story ever written. Sorry, this is not open to debate. Don't come at me with Year One, The Long Halloween or Knightfall, fine tales though they may all be. Morrison's symbolic, psychologically rich tale is the deepest Batman story ever penned and it was an obvious influence on the excellent Arkham Asylum game. Morrison's Arkham is almost ... radiant. Meanwhile, here's a serious song on serious Earth.
