The introduction of Harley Quinn is a quick, fun read. Harley matches the Joker for insanity, and the technicolour campness of the villains is a nice counterpoint to Batman's brooding, almost humourless, determination. The writing is workmanlike, and the art good if not spectacular; bright and energetic with the focus - as it should be - on Harley, who is cute-sexy and mad as a blue fish, the ultimate nightmare crazy girlfriend.
