I liked the characters, the crew members of Harleen, especially Jocker( the same old one from Batman: The Animated Series) with rawness and unpredictability who takes advantage of Harleen's soft spot for him. But, Ivy as a friend is making her realise that he no good...
It is fun story about, Harleen and Ivy's friendship and how Harleen getting along with her gang to prove herself she is something at Gotham and doing well without Jocker, which has fun dialogues and cool action. All-in-all I like it.
