Art: The art work is so fantastic with vibrant colors and expressive features. The spread is gorgeous and Batman is drawn very well. 
 The story as such is straight forward. Black glove decides to attack Batman by making him insane. Its a pretty good idea though it has a lot of flaws in planning but it all works out in the end. The story gets cluttered when Joker is added to the mixture. I like Joker and Morrison does a good with him being sane amidst all the insanity. 
 Its good I read it as TPB as I could read quickly and get over the confusion quickly. Its a major drawback in writing when insanity becomes running theme and the character's behavior doesn't catch up with context. Morrison pulls it off in some places but it doesn't work for a major chunk of the story. 
 Its a decent read with brilliant art, compelling storyline and chaotic setting. If you are into that kind of thing, that is.
