I read DKSA several years back after finishing a Miller TPB that had Year One and Returns, as well as another, I think Halloween themed comic.
I read a few negative things about DKSA but figured how can it not be good, after DKR? I don't really remember much about it at all, I remember it being a bit of a struggle to get through, the art wasn't great, I think Dick Grayson's portrayal left a bad impression.
But, that's a good question. I wonder how much it could be improved if somebody else went back and completely re-illustrate the entire thing, with more attention to detail.
I need to go back and re-read it, cause now I'm thinking I may appreciate it more than I did at the time I read it. How can it not be good, after DKR? Haha
