No idea what happened here; I liked volume one, but this collection was a jumble of nonsense. She goes to Comic-Con, which is kind of a great idea, but I guess you have to know all the DC names for it to be really interesting? I don't know; I was skimming at that point. There were aspects of her team-up with Power Girl that I loved, but mostly it was boob joke after boob joke after boob joke, and let's give that a rest already, can we please? I liked the origin story, but the rest of it was just blah--especially the dialogue. "Holy tuck an' rolee," "unfinished beeswax," gaaaag me with a spoon. Also: they seem to switch artists a lot and I really got impatient with that. I might like to try out a different run of Harley Quinn comics, but I think I'm done with this one.
