Grant Morrison work on Batman did for the Caped Crusader what O'Neil and Adam's did for Batman in the 70s and what Frank Miller did for Batman in the eighties. His run on the character redefined him for the twenty first century. Without Grant Morrison there would not have been Scott Snyder nor Tom King. And what I consider to be the proudest achievement of Morrison take on the Dark Knight was...
Batman Incorporated
Shame it lasted so briefly...
Which begs the question, how would you ressurect Batman Inc. (Creative Teams very much appreciated)
