Granted, I haven't read many Batman books (I usually stay away from superhero comics) but this has got to be the worst. It is in a alternate timeline/universe which could have been pretty interesting. The alternate take on the Joker was at least interesting. The artwork was sometimes ok but sometimes i just wondered if the artist were drunk. The perspectives, proportions, poses and other things were really wonky. Batman's cape can apparently alter it's size depending on the dramatic flare of the scene. 
 The writing was generally pretty terrible as well. 
 Kind of disappointed I read it I think.
