I remember waiting to floored, expecting at least to be amused. I read it in one sitting and then I read some Nancy Drew to clean my brain.
The combination of ugly art, bad writing, and themes worthy of a 15-year-old boy on crack just didn't do it for me. Batman reminded me too much of Cable, Catwoman was too pathetic, the Joker was... blah. I thought the mutant gangs were pretty hilarious, although I don't think that was what Miller was going for.
I did have one pretty weird dream with DKR!Batman threatening to kill me if I didn't paint a picture of him, but other than that I was unaffected.
