I enjoyed this for what it was; I've read so many interpretations of the Joker over the years, and while I don't particularly love "homicidal maniac Joker," it's not like I don't understand that this is an interpretation that some people prefer, or like to write about.
One thing I realized while reading this issue, though: Scott Snyder's Jim Gordon Jr., as drawn by Jock, was infinitely scarier. The issue of Detective, "Skeleton Key," is without a doubt one of the creepiest damn things I've ever read and, to be honest, no Joker story I've read thus far compares to that.
I have viewed Greg Capullo's artwork generally favorably over this run, but for some reason, I wasn't feeling it this issue. Nothing I could put my finger on, but I wonder if Capullo's style simply doesn't mesh with this kind of story. That's not a criticism; for example, Frank Miller's artwork was perfect for Daredevil and Dark Knight, but it likely wouldn't have been as effective on a book like, say, Adam Strange or something like that.
