The overall issue is very good and worth the read. The cover features Harley, so you know she is going to be in it. I can say that I believe the art was edited after the hype of the Bat-a-wang from last issue.
With that said, there is a lot of rape imagery going on this issue. This also leads me to believe the art and story was edited to avoid more adult situations.
First off, love the Ramones reference. Batman meet Harley, Harley beat Batman.
