Had hoped for more. It turned out to be just okay but a decent enough issue and thankfully selfcontained. It could have been as easily packaged as the Blackest Night crossover for Gotham Sirens with Harley and Ivy as prominent as they were. And the watercolor-like artstyle and action was okay in some panels.
Decent enough was:
-Black Mask recap in the mandatory BN memory download
-Selina characterization true to her missed series
-Ivy deals with the BM in a appropriately grizzly manor
-Maggie Kyle's origin into a potential supervillainess
